[SPARK-19402][DOCS] Support LaTex inline formula correctly and fix warnings in Scala/Java APIs generation
## What changes were proposed in this pull request?

This PR proposes three things as below:

- Support LaTex inline-formula, `\( ... \)` in Scala API documentation
  It seems currently,

  ```
  \( ... \)
  ```

  are rendered as they are, for example,

  <img width="345" alt="2017-01-30 10 01 13" src="https://cloud.githubusercontent.com/assets/6477701/22423960/ab37d54a-e737-11e6-9196-4f6229c0189c.png">

  It seems mistakenly more backslashes were added.

- Fix warnings Scaladoc/Javadoc generation
  This PR fixes t two types of warnings as below:

  ```

Burak Yavuz 081b7addaf [SPARK-19378][SS] Ensure continuity of stateOperator and eventTime metrics even if there is no new data in trigger
## What changes were proposed in this pull request?

In StructuredStreaming, if a new trigger was skipped because no new data arrived, we suddenly report nothing for the metrics `stateOperator`. We could however easily report the metrics from `lastExecution` to ensure continuity of metrics.

gatorsmile f9156d2956 [SPARK-19406][SQL] Fix function to_json to respect user-provided options
### What changes were proposed in this pull request?
Currently, the function `to_json` allows users to provide options for generating JSON. However, it does not pass it to `JacksonGenerator`. Thus, it ignores the user-provided options. This PR is to fix it. Below is an example.

```Scala
val df = Seq(Tuple1(Tuple1(java.sql.Timestamp.valueOf("2015-08-26 18:00:00.0")))).toDF("a")
val options = Map("timestampFormat" -> "dd/MM/yyyy HH:mm")
df.select(to_json($"a", options)).show(false)
```
The current output is like
```
+--------------------------------------+
|structtojson(a)                       |
+--------------------------------------+
|{"_1":"2015-08-26T18:00:00.000-07:00"}|
+--------------------------------------+
```

After the fix, the output is like
```
+-------------------------+
|structtojson(a)          |
+-------------------------+
|{"_1":"26/08/2015 18:00"}|
+-------------------------+
```
### How was this patch tested?

Wenchen Fan f7c07db852 [SPARK-19152][SQL][FOLLOWUP] simplify CreateHiveTableAsSelectCommand
## What changes were proposed in this pull request?

After https://github.com/apache/spark/pull/16552 , `CreateHiveTableAsSelectCommand` becomes very similar to `CreateDataSourceTableAsSelectCommand`, and we can further simplify it by only creating table in the table-not-exist branch.

This PR also adds hive provider checking in DataStream reader/writer, which is missed in #16552

Takuya UESHIN 2969fb4370 [SPARK-18936][SQL] Infrastructure for session local timezone support.
## What changes were proposed in this pull request?

As of Spark 2.1, Spark SQL assumes the machine timezone for datetime manipulation, which is bad if users are not in the same timezones as the machines, or if different users have different timezones.

We should introduce a session local timezone setting that is used for execution.

An explicit non-goal is locale handling.

### Semantics

Setting the session local timezone means that the timezone-aware expressions listed below should use the timezone to evaluate values, and also it should be used to convert (cast) between string and timestamp or between timestamp and date.

- `CurrentDate`
- `CurrentBatchTimestamp`
- `Hour`
- `Minute`
- `Second`
- `DateFormatClass`
- `ToUnixTimestamp`
- `UnixTimestamp`
- `FromUnixTime`

and below are implicitly timezone-aware through cast from timestamp to date:

- `DayOfYear`
- `Year`
- `Quarter`
- `Month`
- `DayOfMonth`
- `WeekOfYear`
- `LastDay`
- `NextDay`
- `TruncDate`

For example, if you have timestamp `"2016-01-01 00:00:00"` in `GMT`, the values evaluated by some of timezone-aware expressions are:

```scala
scala> val df = Seq(new java.sql.Timestamp(1451606400000L)).toDF("ts")
df: org.apache.spark.sql.DataFrame = [ts: timestamp]

scala> df.selectExpr("cast(ts as string)", "year(ts)", "month(ts)", "dayofmonth(ts)", "hour(ts)", "minute(ts)", "second(ts)").show(truncate = false)
+-------------------+----------------------+-----------------------+----------------------------+--------+----------+----------+
|ts                 |year(CAST(ts AS DATE))|month(CAST(ts AS DATE))|dayofmonth(CAST(ts AS DATE))|hour(ts)|minute(ts)|second(ts)|
+-------------------+----------------------+-----------------------+----------------------------+--------+----------+----------+
|2016-01-01 00:00:00|2016                  |1                      |1                           |0       |0         |0         |
+-------------------+----------------------+-----------------------+----------------------------+--------+----------+----------+
```

whereas setting the session local timezone to `"PST"`, they are:

```scala
scala> spark.conf.set("spark.sql.session.timeZone", "PST")

scala> df.selectExpr("cast(ts as string)", "year(ts)", "month(ts)", "dayofmonth(ts)", "hour(ts)", "minute(ts)", "second(ts)").show(truncate = false)
+-------------------+----------------------+-----------------------+----------------------------+--------+----------+----------+
|ts                 |year(CAST(ts AS DATE))|month(CAST(ts AS DATE))|dayofmonth(CAST(ts AS DATE))|hour(ts)|minute(ts)|second(ts)|
+-------------------+----------------------+-----------------------+----------------------------+--------+----------+----------+
|2015-12-31 16:00:00|2015                  |12                     |31                          |16      |0         |0         |
+-------------------+----------------------+-----------------------+----------------------------+--------+----------+----------+
```

Notice that even if you set the session local timezone, it affects only in `DataFrame` operations, neither in `Dataset` operations, `RDD` operations nor in `ScalaUDF`s. You need to properly handle timezone by yourself.

### Design of the fix

I introduced an analyzer to pass session local timezone to timezone-aware expressions and modified DateTimeUtils to take the timezone argument.

## How was this patch tested?

Existing tests and added tests for timezone aware expressions.

Dilip Biswal 9effc2cdcb [TESTS][SQL] Setup testdata at the beginning for tests to run independently
## What changes were proposed in this pull request?

In CachedTableSuite, we are not setting up the test data at the beginning. Some tests fail while trying to run individually. When running the entire suite they run fine.

Here are some of the tests that fail -

- test("SELECT star from cached table")
- test("Self-join cached")

As part of this simplified a couple of tests by calling a support method to count the number of
InMemoryRelations.

## How was this patch tested?

Ran the failing tests individually.

Kousuke Saruta 15ef3740de [SPARK-19334][SQL] Fix the code injection vulnerability related to Generator functions.
## What changes were proposed in this pull request?

Similar to SPARK-15165, codegen is in danger of arbitrary code injection. The root cause is how variable names are created by codegen.
In GenerateExec#codeGenAccessor, a variable name is created like as follows.

```
val value = ctx.freshName(name)
```

The variable `value` is named based on the value of the variable `name` and the value of `name` is from schema given by users so an attacker can attack with queries like as follows.

```
SELECT inline(array(cast(struct(1) AS struct<`=new Object() { {f();} public void f() {throw new RuntimeException("This exception is injected.");} public int x;}.x`:int>)))
```

In the example above, a RuntimeException is thrown but an attacker can replace it with arbitrary code.

## How was this patch tested?

Added a new test case.

Nattavut Sutyanyong cdb691eb4d [SPARK-19017][SQL] NOT IN subquery with more than one column may return incorrect results
## What changes were proposed in this pull request?

This PR fixes the code in Optimizer phase where the NULL-aware expression of a NOT IN query is expanded in Rule `RewritePredicateSubquery`.

Example:
The query

 select a1,b1
 from   t1
 where  (a1,b1) not in (select a2,b2
                        from   t2);

has the (a1, b1) = (a2, b2) rewritten from (before this fix):

Join LeftAnti, ((isnull((_1#2 = a2#16)) || isnull((_2#3 = b2#17))) || ((_1#2 = a2#16) && (_2#3 = b2#17)))

to (after this fix):

Join LeftAnti, (((_1#2 = a2#16) || isnull((_1#2 = a2#16))) && ((_2#3 = b2#17) || isnull((_2#3 = b2#17))))

Wenchen Fan 59c184e028 [SPARK-17913][SQL] compare atomic and string type column may return confusing result
## What changes were proposed in this pull request?

Spark SQL follows MySQL to do the implicit type conversion for binary comparison: http://dev.mysql.com/doc/refman/5.7/en/type-conversion.html

However, this may return confusing result, e.g. `1 = 'true'` will return true, `19157170390056973L = '19157170390056971'` will return true.

I think it's more reasonable to follow postgres in this case, i.e. cast string to the type of the other side, but return null if the string is not castable to keep hive compatibility.

## How was this patch tested?

newly added tests.

hyukjinkwon e576c1ed79 [SPARK-9435][SQL] Reuse function in Java UDF to correctly support expressions that require equality comparison between ScalaUDF
## What changes were proposed in this pull request?

Currently, running the codes in Java

```java
spark.udf().register("inc", new UDF1<Long, Long>() {
  Override
  public Long call(Long i) {
    return i + 1;
  }
}, DataTypes.LongType);

spark.range(10).toDF("x").createOrReplaceTempView("tmp");
Row result = spark.sql("SELECT inc(x) FROM tmp GROUP BY inc(x)").head();
Assert.assertEquals(7, result.getLong(0));
```

fails as below:

```
org.apache.spark.sql.AnalysisException: expression 'tmp.`x`' is neither present in the group by, nor is it an aggregate function. Add to group by or wrap in first() (or first_value) if you don't care which value you get.;;
Aggregate [UDF(x#19L)], [UDF(x#19L) AS UDF(x)#23L]
+- SubqueryAlias tmp, `tmp`
   +- Project [id#16L AS x#19L]
      +- Range (0, 10, step=1, splits=Some(8))

	at org.apache.spark.sql.catalyst.analysis.CheckAnalysis$class.failAnalysis(CheckAnalysis.scala:40)
	at org.apache.spark.sql.catalyst.analysis.Analyzer.failAnalysis(Analyzer.scala:57)
```

The root cause is because we were creating the function every time when it needs to build as below:

```scala
scala> def inc(i: Int) = i + 1
inc: (i: Int)Int

scala> (inc(_: Int)).hashCode
res15: Int = 1231799381

scala> (inc(_: Int)).hashCode
res16: Int = 2109839984

scala> (inc(_: Int)) == (inc(_: Int))
res17: Boolean = false
```

This seems leading to the comparison failure between `ScalaUDF`s created from Java UDF API, for example, in `Expression.semanticEquals`.

In case of Scala one, it seems already fine.

Both can be tested easily as below if any reviewer is more comfortable with Scala:

```scala
val df = Seq((1, 10), (2, 11), (3, 12)).toDF("x", "y")
val javaUDF = new UDF1[Int, Int]  {
  override def call(i: Int): Int = i + 1
}

jiangxingbo 3bdf3ee860 [SPARK-19272][SQL] Remove the param viewOriginalText from CatalogTable
## What changes were proposed in this pull request?

Hive will expand the view text, so it needs 2 fields: originalText and viewText. Since we don't expand the view text, but only add table properties, perhaps only a single field `viewText` is enough in CatalogTable.

This PR brought in the following changes:
1. Remove the param `viewOriginalText` from `CatalogTable`;
2. Update the output of command `DescribeTableCommand`.

## How was this patch tested?

Tested by exsiting test cases, also updated the failed test cases.

Wenchen Fan fcfd5d0bba [SPARK-19290][SQL] add a new extending interface in Analyzer for post-hoc resolution
## What changes were proposed in this pull request?

To implement DDL commands, we added several analyzer rules in sql/hive module to analyze DDL related plans. However, our `Analyzer` currently only have one extending interface: `extendedResolutionRules`, which defines extra rules that will be run together with other rules in the resolution batch, and doesn't fit DDL rules well, because:

1. DDL rules may do some checking and normalization, but we may do it many times as the resolution batch will run rules again and again, until fixed point, and it's hard to tell if a DDL rule has already done its checking and normalization. It's fine because DDL rules are idempotent, but it's bad for analysis performance
2. some DDL rules may depend on others, and it's pretty hard to write `if` conditions to guarantee the dependencies. It will be good if we have a batch which run rules in one pass, so that we can guarantee the dependencies by rules order.

This PR adds a new extending interface in `Analyzer`: `postHocResolutionRules`, which defines rules that will be run only once in a batch runs right after the resolution batch.

Dongjoon Hyun c4a6519c44 [SPARK-19218][SQL] Fix SET command to show a result correctly and in a sorted order
## What changes were proposed in this pull request?

This PR aims to fix the following two things.

1. `sql("SET -v").collect()` or `sql("SET -v").show()` raises the following exceptions for String configuration with default value, `null`. For the test, please see [Jenkins result](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/71539/testReport/) and 60953bf1f1 in #16624 .

```
sbt.ForkMain$ForkError: java.lang.RuntimeException: Error while decoding: java.lang.NullPointerException
createexternalrow(input[0, string, false].toString, input[1, string, false].toString, input[2, string, false].toString, StructField(key,StringType,false), StructField(value,StringType,false), StructField(meaning,StringType,false))
:- input[0, string, false].toString
:  +- input[0, string, false]
:- input[1, string, false].toString
:  +- input[1, string, false]
+- input[2, string, false].toString
   +- input[2, string, false]
```

2. Currently, `SET` and `SET -v` commands show unsorted result.
    We had better show a sorted result for UX. Also, this is compatible with Hive.

Wenchen Fan de6ad3dfa7 [SPARK-19309][SQL] disable common subexpression elimination for conditional expressions
## What changes were proposed in this pull request?

As I pointed out in https://github.com/apache/spark/pull/15807#issuecomment-259143655 , the current subexpression elimination framework has a problem, it always evaluates all common subexpressions at the beginning, even they are inside conditional expressions and may not be accessed.

Ideally we should implement it like scala lazy val, so we only evaluate it when it gets accessed at lease once. https://github.com/apache/spark/issues/15837 tries this approach, but it seems too complicated and may introduce performance regression.

This PR simply stops common subexpression elimination for conditional expressions, with some cleanup.

hyukjinkwon 74e65cb74a [SPARK-16101][SQL] Refactoring CSV read path to be consistent with JSON data source
## What changes were proposed in this pull request?

This PR refactors CSV read path to be consistent with JSON data source. It makes the methods in classes have consistent arguments with JSON ones.

`UnivocityParser` and `JacksonParser`

``` scala
private[csv] class UnivocityParser(
    schema: StructType,
    requiredSchema: StructType,
    options: CSVOptions) extends Logging {
  ...

def parse(input: String): Seq[InternalRow] = {
  ...
```

``` scala
class JacksonParser(
    schema: StructType,
    columnNameOfCorruptRecord: String,
    options: JSONOptions) extends Logging {
  ...

def parse(input: String): Option[InternalRow] = {
  ...
```

These allow parsing an iterator (`String` to `InternalRow`) as below for both JSON and CSV:

```scala
iter.flatMap(parser.parse)
```

Wenchen Fan 3c2ba9fcc4 [SPARK-19305][SQL] partitioned table should always put partition columns at the end of table schema
## What changes were proposed in this pull request?

For data source tables, we will always reorder the specified table schema, or the query in CTAS, to put partition columns at the end. e.g. `CREATE TABLE t(a int, b int, c int, d int) USING parquet PARTITIONED BY (d, b)` will create a table with schema `<a, c, d, b>`

Hive serde tables don't have this problem before, because its CREATE TABLE syntax specifies data schema and partition schema individually.

However, after we unifed the CREATE TABLE syntax, Hive serde table also need to do the reorder. This PR puts the reorder logic in a analyzer rule,  which works with both data source tables and Hive serde tables.

## What changes were proposed in this pull request?

When we query a table with a filter on partitioned columns, we will push the partition filter to the metastore to get matched partitions directly.

In `HiveExternalCatalog.listPartitionsByFilter`, we assume the column names in partition filter are already normalized and we don't need to consider case sensitivity. However, `HiveTableScanExec` doesn't follow this assumption. This PR fixes it.

Kazuaki Ishizaki 148a84b370 [SPARK-17912] [SQL] Refactor code generation to get data for ColumnVector/ColumnarBatch
## What changes were proposed in this pull request?

This PR refactors the code generation part to get data from `ColumnarVector` and `ColumnarBatch` by using a trait `ColumnarBatchScan` for ease of reuse. This is because this part will be reused by several components (e.g. parquet reader, Dataset.cache, and others) since `ColumnarBatch` will be first citizen.

This PR is a part of https://github.com/apache/spark/pull/15219. In advance, this PR makes the code generation for  `ColumnarVector` and `ColumnarBatch` reuseable as a trait. In general, this is very useful for other components from the reuseability view, too.

Wenchen Fan 2e62560024 [SPARK-19265][SQL] make table relation cache general and does not depend on hive
## What changes were proposed in this pull request?

We have a table relation plan cache in `HiveMetastoreCatalog`, which caches a lot of things: file status, resolved data source, inferred schema, etc.

However, it doesn't make sense to limit this cache with hive support, we should move it to SQL core module so that users can use this cache without hive support.

It can also reduce the size of `HiveMetastoreCatalog`, so that it's easier to remove it eventually.

1. move the table relation cache to `SessionCatalog`
2. `SessionCatalog.lookupRelation` will return `SimpleCatalogRelation` and the analyzer will convert it to `LogicalRelation` or `MetastoreRelation` later, then `HiveSessionCatalog` doesn't need to override `lookupRelation` anymore
3. `FindDataSourceTable` will read/write the table relation cache.

Shixiong Zhu c050c12274 [SPARK-19113][SS][TESTS] Ignore StreamingQueryException thrown from awaitInitialization to avoid breaking tests
## What changes were proposed in this pull request?

#16492 missed one race condition: `StreamExecution.awaitInitialization` may throw fatal errors and fail the test. This PR just ignores `StreamingQueryException` thrown from `awaitInitialization` so that we can verify the exception in the `ExpectFailure` action later. It's fine since `StopStream` or `ExpectFailure` will catch `StreamingQueryException` as well.

jiangxingbo f85f29608d [SPARK-19024][SQL] Implement new approach to write a permanent view
## What changes were proposed in this pull request?

On CREATE/ALTER a view, it's no longer needed to generate a SQL text string from the LogicalPlan, instead we store the SQL query text、the output column names of the query plan, and current database to CatalogTable. Permanent views created by this approach can be resolved by current view resolution approach.

The main advantage includes:
1. If you update an underlying view, the current view also gets updated;
2. That gives us a change to get ride of SQL generation for operators.

Major changes of this PR:
1. Generate the view-specific properties(e.g. view default database, view query output column names) during permanent view creation and store them as properties in the CatalogTable;
2. Update the commands `CreateViewCommand` and `AlterViewAsCommand`, get rid of SQL generation from them.

Wenchen Fan 4494cd9716 [SPARK-18243][SQL] Port Hive writing to use FileFormat interface
## What changes were proposed in this pull request?

Inserting data into Hive tables has its own implementation that is distinct from data sources: `InsertIntoHiveTable`, `SparkHiveWriterContainer` and `SparkHiveDynamicPartitionWriterContainer`.

Note that one other major difference is that data source tables write directly to the final destination without using some staging directory, and then Spark itself adds the partitions/tables to the catalog. Hive tables actually write to some staging directory, and then call Hive metastore's loadPartition/loadTable function to load those data in. So we still need to keep `InsertIntoHiveTable` to put this special logic. In the future, we should think of writing to the hive table location directly, so that we don't need to call `loadTable`/`loadPartition` at the end and remove `InsertIntoHiveTable`.

This PR removes `SparkHiveWriterContainer` and `SparkHiveDynamicPartitionWriterContainer`, and create a `HiveFileFormat` to implement the write logic. In the future, we should also implement the read logic in `HiveFileFormat`.

Liang-Chi Hsieh 61e48f52d1 [SPARK-19082][SQL] Make ignoreCorruptFiles work for Parquet
## What changes were proposed in this pull request?

We have a config `spark.sql.files.ignoreCorruptFiles` which can be used to ignore corrupt files when reading files in SQL. Currently the `ignoreCorruptFiles` config has two issues and can't work for Parquet:

1. We only ignore corrupt files in `FileScanRDD` . Actually, we begin to read those files as early as inferring data schema from the files. For corrupt files, we can't read the schema and fail the program. A related issue reported at http://apache-spark-developers-list.1001551.n3.nabble.com/Skip-Corrupted-Parquet-blocks-footer-tc20418.html
2. In `FileScanRDD`, we assume that we only begin to read the files when starting to consume the iterator. However, it is possibly the files are read before that. In this case, `ignoreCorruptFiles` config doesn't work too.

This patch targets Parquet datasource. If this direction is ok, we can address the same issue for other datasources like Orc.

Two main changes in this patch:

1. Replace `ParquetFileReader.readAllFootersInParallel` by implementing the logic to read footers in multi-threaded manner

    We can't ignore corrupt files if we use `ParquetFileReader.readAllFootersInParallel`. So this patch implements the logic to do the similar thing in `readParquetFootersInParallel`.

2. In `FileScanRDD`, we need to ignore corrupt file too when we call `readFunction` to return iterator.

One thing to notice is:

We read schema from Parquet file's footer. The method to read footer `ParquetFileReader.readFooter` throws `RuntimeException`, instead of `IOException`, if it can't successfully read the footer. Please check out df9d8e4154/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetFileReader.java (L470). So this patch catches `RuntimeException`.  One concern is that it might also shadow other runtime exceptions other than reading corrupt files.

## How was this patch tested?

Jenkins tests.

gatorsmile de62ddf7ff [SPARK-19120] Refresh Metadata Cache After Loading Hive Tables
### What changes were proposed in this pull request?
```Scala
        sql("CREATE TABLE tab (a STRING) STORED AS PARQUET")

        // This table fetch is to fill the cache with zero leaf files
        spark.table("tab").show()

        sql(
          s"""
             |LOAD DATA LOCAL INPATH '$newPartitionDir' OVERWRITE
             |INTO TABLE tab
           """.stripMargin)

        spark.table("tab").show()
```

In the above example, the returned result is empty after table loading. The metadata cache could be out of dated after loading new data into the table, because loading/inserting does not update the cache. So far, the metadata cache is only used for data source tables. Thus, for Hive serde tables, only `parquet` and `orc` formats are facing such issues, because the Hive serde tables in the format of  parquet/orc could be converted to data source tables when `spark.sql.hive.convertMetastoreParquet`/`spark.sql.hive.convertMetastoreOrc` is on.

This PR is to refresh the metadata cache after processing the `LOAD DATA` command.

In addition, Spark SQL does not convert **partitioned** Hive tables (orc/parquet) to data source tables in the write path, but the read path is using the metadata cache for both **partitioned** and non-partitioned Hive tables (orc/parquet). That means, writing the partitioned parquet/orc tables still use `InsertIntoHiveTable`, instead of `InsertIntoHadoopFsRelationCommand`. To avoid reading the out-of-dated cache, `InsertIntoHiveTable` needs to refresh the metadata cache for partitioned tables. Note, it does not need to refresh the cache for non-partitioned parquet/orc tables, because it does not call `InsertIntoHiveTable` at all. Based on the comments, this PR will keep the existing logics unchanged. That means, we always refresh the table no matter whether the table is partitioned or not.

Wenchen Fan 6b34e745bb [SPARK-19178][SQL] convert string of large numbers to int should return null
## What changes were proposed in this pull request?

When we convert a string to integral, we will convert that string to `decimal(20, 0)` first, so that we can turn a string with decimal format to truncated integral, e.g. `CAST('1.2' AS int)` will return `1`.

However, this brings problems when we convert a string with large numbers to integral, e.g. `CAST('1234567890123' AS int)` will return `1912276171`, while Hive returns null as we expected.

This is a long standing bug(seems it was there the first day Spark SQL was created), this PR fixes this bug by adding the native support to convert `UTF8String` to integral.

jiangxingbo 30a07071f0 [SPARK-18801][SQL] Support resolve a nested view
## What changes were proposed in this pull request?

We should be able to resolve a nested view. The main advantage is that if you update an underlying view, the current view also gets updated.
The new approach should be compatible with older versions of SPARK/HIVE, that means:
1. The new approach should be able to resolve the views that created by older versions of SPARK/HIVE;
2. The new approach should be able to resolve the views that are currently supported by SPARK SQL.

The new approach mainly brings in the following changes:
1. Add a new operator called `View` to keep track of the CatalogTable that describes the view, and the output attributes as well as the child of the view;
2. Update the `ResolveRelations` rule to resolve the relations and views, note that a nested view should be resolved correctly;
3. Add `viewDefaultDatabase` variable to `CatalogTable` to keep track of the default database name used to resolve a view, if the `CatalogTable` is not a view, then the variable should be `None`;
4. Add `AnalysisContext` to enable us to still support a view created with CTE/Windows query;
5. Enables the view support without enabling Hive support (i.e., enableHiveSupport);
6. Fix a weird behavior: the result of a view query may have different schema if the referenced table has been changed. After this PR, we try to cast the child output attributes to that from the view schema, throw an AnalysisException if cast is not allowed.

Note this is compatible with the views defined by older versions of Spark(before 2.2), which have empty `defaultDatabase` and all the relations in `viewText` have database part defined.

## How was this patch tested?
1. Add new tests in `SessionCatalogSuite` to test the function `lookupRelation`;
2. Add new test case in `SQLViewSuite` to test resolve a nested view.

[SPARK-19113][SS][TESTS] Set UncaughtExceptionHandler in onQueryStarted to ensure catching fatal errors during query initialization
## What changes were proposed in this pull request?

StreamTest sets `UncaughtExceptionHandler` after starting the query now. It may not be able to catch fatal errors during query initialization. This PR uses `onQueryStarted` callback to fix it.

## How was this patch tested?

[SPARK-18857][SQL] Don't use Iterator.duplicate for incrementalCollect in Thrift Server
## What changes were proposed in this pull request?

To support `FETCH_FIRST`, SPARK-16563 used Scala `Iterator.duplicate`. However,
Scala `Iterator.duplicate` uses a **queue to buffer all items between both iterators**,
this causes GC and hangs for queries with large number of rows. We should not use this,
especially for `spark.sql.thriftServer.incrementalCollect`.

https://github.com/scala/scala/blob/2.12.x/src/library/scala/collection/Iterator.scala#L1262-L1300

## How was this patch tested?

Pass the existing tests.

Wenchen Fan b0319c2ecb [SPARK-19107][SQL] support creating hive table with DataFrameWriter and Catalog
## What changes were proposed in this pull request?

After unifying the CREATE TABLE syntax in https://github.com/apache/spark/pull/16296, it's pretty easy to support creating hive table with `DataFrameWriter` and `Catalog` now.

This PR basically just removes the hive provider check in `DataFrameWriter.saveAsTable` and `Catalog.createExternalTable`, and add tests.

Burak Yavuz faabe69cc0 [SPARK-18952] Regex strings not properly escaped in codegen for aggregations
## What changes were proposed in this pull request?

If I use the function regexp_extract, and then in my regex string, use `\`, i.e. escape character, this fails codegen, because the `\` character is not properly escaped when codegen'd.

Example stack trace:
```
/* 059 */     private int maxSteps = 2;
/* 060 */     private int numRows = 0;
/* 061 */     private org.apache.spark.sql.types.StructType keySchema = new org.apache.spark.sql.types.StructType().add("date_format(window#325.start, yyyy-MM-dd HH:mm)", org.apache.spark.sql.types.DataTypes.StringType)
/* 062 */     .add("regexp_extract(source#310.description, ([a-zA-Z]+)\[.*, 1)", org.apache.spark.sql.types.DataTypes.StringType);
/* 063 */     private org.apache.spark.sql.types.StructType valueSchema = new org.apache.spark.sql.types.StructType().add("sum", org.apache.spark.sql.types.DataTypes.LongType);
/* 064 */     private Object emptyVBase;

...

org.codehaus.commons.compiler.CompileException: File 'generated.java', Line 62, Column 58: Invalid escape sequence

In the codegend expression, the literal should use `\\` instead of `\`

Wenchen Fan b3d39620c5 [SPARK-19085][SQL] cleanup OutputWriterFactory and OutputWriter
## What changes were proposed in this pull request?

`OutputWriterFactory`/`OutputWriter` are internal interfaces and we can remove some unnecessary APIs:
1. `OutputWriterFactory.newWriter(path: String)`: no one calls it and no one implements it.
2. `OutputWriter.write(row: Row)`: during execution we only call `writeInternal`, which is weird as `OutputWriter` is already an internal interface. We should rename `writeInternal` to `write` and remove `def write(row: Row)` and it's related converter code. All implementations should just implement `def write(row: InternalRow)`

Michal Senkyr 903bb8e8a2 [SPARK-16792][SQL] Dataset containing a Case Class with a List type causes a CompileException (converting sequence to list)
## What changes were proposed in this pull request?

Added a `to` call at the end of the code generated by `ScalaReflection.deserializerFor` if the requested type is not a supertype of `WrappedArray[_]` that uses `CanBuildFrom[_, _, _]` to convert result into an arbitrary subtype of `Seq[_]`.

Care was taken to preserve the original deserialization where it is possible to avoid the overhead of conversion in cases where it is not needed

`ScalaReflection.serializerFor` could already be used to serialize any `Seq[_]` so it was not altered

`SQLImplicits` had to be altered and new implicit encoders added to permit serialization of other sequence types

Also fixes [SPARK-16815] Dataset[List[T]] leads to ArrayStoreException

## How was this patch tested?
```bash
./build/mvn -DskipTests clean package && ./dev/run-tests
```

Also manual execution of the following sets of commands in the Spark shell:
```scala
case class TestCC(key: Int, letters: List[String])

val ds1 = sc.makeRDD(Seq(
(List("D")),
(List("S","H")),
(List("F","H")),
(List("D","L","L"))
)).map(x=>(x.length,x)).toDF("key","letters").as[TestCC]

val test1=ds1.map{_.key}
test1.show
```

```scala
case class X(l: List[String])
spark.createDataset(Seq(List("A"))).map(X).show
```

```scala
spark.sqlContext.createDataset(sc.parallelize(List(1) :: Nil)).collect
```

After adding arbitrary sequence support also tested with the following commands:

```scala
case class QueueClass(q: scala.collection.immutable.Queue[Int])

spark.createDataset(Seq(List(1,2,3))).map(x => QueueClass(scala.collection.immutable.Queue(x: _*))).map(_.q.dequeue).collect

Kevin Yu bcc510b021 [SPARK-18871][SQL] New test cases for IN/NOT IN subquery
## What changes were proposed in this pull request?
This PR extends the existing IN/NOT IN subquery test cases coverage, adds more test cases to the IN subquery test suite.

Based on the discussion, we will create  `subquery/in-subquery` sub structure under `sql/core/src/test/resources/sql-tests/inputs` directory.

This is the high level grouping for IN subquery:

`subquery/in-subquery/`
`subquery/in-subquery/simple-in.sql`
`subquery/in-subquery/in-group-by.sql (in parent side, subquery, and both)`
`subquery/in-subquery/not-in-group-by.sql`
`subquery/in-subquery/in-order-by.sql`
`subquery/in-subquery/in-limit.sql`
`subquery/in-subquery/in-having.sql`
`subquery/in-subquery/in-joins.sql`
`subquery/in-subquery/not-in-joins.sql`
`subquery/in-subquery/in-set-operations.sql`
`subquery/in-subquery/in-with-cte.sql`
`subquery/in-subquery/not-in-with-cte.sql`
subquery/in-subquery/in-multiple-columns.sql`

We will deliver it through multiple prs, this is the first pr for the IN subquery, it has

`subquery/in-subquery/simple-in.sql`
`subquery/in-subquery/in-group-by.sql (in parent side, subquery, and both)`

These are the results from running on DB2.

Wenchen Fan cca945b6aa [SPARK-18885][SQL] unify CREATE TABLE syntax for data source and hive serde tables
## What changes were proposed in this pull request?

Today we have different syntax to create data source or hive serde tables, we should unify them to not confuse users and step forward to make hive a data source.

Please read https://issues.apache.org/jira/secure/attachment/12843835/CREATE-TABLE.pdf for  details.

TODO(for follow-up PRs):
1. TBLPROPERTIES is not added to the new syntax, we should decide if we wanna add it later.
2. `SHOW CREATE TABLE` should be updated to use the new syntax.
3. we should decide if we wanna change the behavior of `SET LOCATION`.

## What changes were proposed in this pull request?

When we append data to a partitioned table with `DataFrameWriter.saveAsTable`, there are 2 issues:
1. doesn't work when the partition has custom location.
2. will recover all partitions

This PR fixes them by moving the special partition handling code from `DataSourceAnalysis` to `InsertIntoHadoopFsRelationCommand`, so that the `DataFrameWriter.saveAsTable` code path can also benefit from it.

Zhenhua Wang ae83c21125 [SPARK-18998][SQL] Add a cbo conf to switch between default statistics and estimated statistics
## What changes were proposed in this pull request?

We add a cbo configuration to switch between default stats and estimated stats.
We also define a new statistics method `planStats` in LogicalPlan with conf as its parameter, in order to pass the cbo switch and other estimation related configurations in the future. `planStats` is used on the caller sides (i.e. in Optimizer and Strategies) to make transformation decisions based on stats.

## How was this patch tested?

Add a test case using a dummy LogicalPlan.

[SPARK-19022][TESTS] Fix tests dependent on OS due to different newline characters
## What changes were proposed in this pull request?

There are two tests failing on Windows due to the different newlines.

```
 - StreamingQueryProgress - prettyJson *** FAILED *** (0 milliseconds)
 "{
    "id" : "39788670-6722-48b7-a248-df6ba08722ac",
    "runId" : "422282f1-3b81-4b47-a15d-82dda7e69390",
    "name" : "myName",
    ...
  }" did not equal "{
    "id" : "39788670-6722-48b7-a248-df6ba08722ac",
    "runId" : "422282f1-3b81-4b47-a15d-82dda7e69390",
    "name" : "myName",
    ...
  }"
  ...
```

```
 - StreamingQueryStatus - prettyJson *** FAILED *** (0 milliseconds)
 "{
    "message" : "active",
    "isDataAvailable" : true,
    "isTriggerActive" : false
  }" did not equal "{
    "message" : "active",
    "isDataAvailable" : true,
    "isTriggerActive" : false
  }"
  ...
```

The reason is, `pretty` in `org.json4s.pretty` writes OS-dependent newlines but the string defined in the tests are `\n`. This ends up with test failures.

This PR proposes to compare these regardless of newline concerns.

Dongjoon Hyun b85e29437d [SPARK-18123][SQL] Use db column names instead of RDD column ones during JDBC Writing
## What changes were proposed in this pull request?

Apache Spark supports the following cases **by quoting RDD column names** while saving through JDBC.
- Allow reserved keyword as a column name, e.g., 'order'.
- Allow mixed-case colume names like the following, e.g., `[a: int, A: int]`.

  ``` scala
  scala> val df = sql("select 1 a, 1 A")
  df: org.apache.spark.sql.DataFrame = [a: int, A: int]
  ...
  scala> df.write.mode("overwrite").format("jdbc").options(option).save()
  scala> df.write.mode("append").format("jdbc").options(option).save()
  ```

This PR aims to use **database column names** instead of RDD column ones in order to support the following additionally.
Note that this case succeeds with `MySQL`, but fails on `Postgres`/`Oracle` before.

``` scala
val df1 = sql("select 1 a")
val df2 = sql("select 1 A")
...
df1.write.mode("overwrite").format("jdbc").options(option).save()
df2.write.mode("append").format("jdbc").options(option).save()
```
## How was this patch tested?

Pass the Jenkins test with a new testcase.

Dongjoon Hyun 752d9eeb9b [SPARK-19012][SQL] Fix createTempViewCommand to throw AnalysisException instead of ParseException
## What changes were proposed in this pull request?

Currently, `createTempView`, `createOrReplaceTempView`, and `createGlobalTempView` show `ParseExceptions` on invalid table names. We had better show better error message. Also, this PR also adds and updates the missing description on the API docs correctly.

**BEFORE**
```
scala> spark.range(10).createOrReplaceTempView("11111")
org.apache.spark.sql.catalyst.parser.ParseException:
mismatched input '11111' expecting {'SELECT', 'FROM', 'ADD', ...}(line 1, pos 0)

== SQL ==
11111
...
```

**AFTER**
```
scala> spark.range(10).createOrReplaceTempView("11111")
org.apache.spark.sql.AnalysisException: Invalid view name: 11111;
...
```

## How was this patch tested?

Wenchen Fan 7d19b6ab7d [SPARK-18567][SQL] Simplify CreateDataSourceTableAsSelectCommand
## What changes were proposed in this pull request?

The `CreateDataSourceTableAsSelectCommand` is quite complex now, as it has a lot of work to do if the table already exists:

1. throw exception if we don't want to ignore it.
2. do some check and adjust the schema if we want to append data.
3. drop the table and create it again if we want to overwrite.

The work 2 and 3 should be done by analyzer, so that we can also apply it to hive tables.

## How was this patch tested?

Kazuaki Ishizaki 93f35569fd [SPARK-16213][SQL] Reduce runtime overhead of a program that creates an primitive array in DataFrame
## What changes were proposed in this pull request?

This PR reduces runtime overhead of a program the creates an primitive array in DataFrame by using the similar approach to #15044. Generated code performs boxing operation in an assignment from InternalRow to an `Object[]` temporary array (at Lines 051 and 061 in the generated code before without this PR). If we know that type of array elements is primitive, we apply the following optimizations:
1. Eliminate a pair of `isNullAt()` and a null assignment
2. Allocate an primitive array instead of `Object[]` (eliminate boxing operations)
3. Create `UnsafeArrayData` by using `UnsafeArrayWriter` to keep a primitive array in a row format instead of doing non-lightweight operations in constructor of `GenericArrayData`
The PR also performs the same things for `CreateMap`.

Here are performance results of [DataFrame programs](6bf54ec5e2/sql/core/src/test/scala/org/apache/spark/sql/execution/benchmark/PrimitiveArrayBenchmark.scala (L83-L112)) by up to 17.9x over without this PR.

gatorsmile 5ac62043cf [SPARK-18992][SQL] Move spark.sql.hive.thriftServer.singleSession to SQLConf
### What changes were proposed in this pull request?

Since `spark.sql.hive.thriftServer.singleSession` is a configuration of SQL component, this conf can be moved from `SparkConf` to `StaticSQLConf`.

When we introduced `spark.sql.hive.thriftServer.singleSession`, all the SQL configuration are session specific. They can be modified in different sessions.

In Spark 2.1, static SQL configuration is added. It is a perfect fit for `spark.sql.hive.thriftServer.singleSession`. Previously, we did the same move for `spark.sql.warehouse.dir` from `SparkConf` to `StaticSQLConf`

Wenchen Fan a05cc425a0 [SPARK-18990][SQL] make DatasetBenchmark fairer for Dataset
## What changes were proposed in this pull request?

Currently `DatasetBenchmark` use `case class Data(l: Long, s: String)` as the record type of `RDD` and `Dataset`, which introduce serialization overhead only to `Dataset` and is unfair.

This PR use `Long` as the record type, to be fairer for `Dataset`

Dongjoon Hyun c2a2069dae [SPARK-19004][SQL] Fix JDBCWriteSuite.testH2Dialect by removing getCatalystType
## What changes were proposed in this pull request?

`JDBCSuite` and `JDBCWriterSuite` have their own `testH2Dialect`s for their testing purposes.

This PR fixes `testH2Dialect` in `JDBCWriterSuite` by removing `getCatalystType` implementation in order to return correct types. Currently, it always returns `Some(StringType)` incorrectly. Note that, for the `testH2Dialect` in `JDBCSuite`, it's intentional because of the test case `Remap types via JdbcDialects`.

## How was this patch tested?

This is a test only update.

Wenchen Fan 8a7db8a608 [SPARK-18980][SQL] implement Aggregator with TypedImperativeAggregate
## What changes were proposed in this pull request?

Currently we implement `Aggregator` with `DeclarativeAggregate`, which will serialize/deserialize the buffer object every time we process an input.

This PR implements `Aggregator` with `TypedImperativeAggregate` and avoids to serialize/deserialize buffer object many times. The benchmark shows we get about 2 times speed up.

For simple buffer object that doesn't need serialization, we still go with `DeclarativeAggregate`, to avoid performance regression.

hyukjinkwon d6cbec7598 [SPARK-18943][SQL] Avoid per-record type dispatch in CSV when reading
## What changes were proposed in this pull request?

`CSVRelation.csvParser` does type dispatch for each value in each row. We can prevent this because the schema is already kept in `CSVRelation`.

So, this PR proposes that converters are created first according to the schema, and then apply them to each.

I just ran some small benchmarks as below after resembling the logics in 7c33b0fd05/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/csv/CSVFileFormat.scala (L170-L178) to test the updated logics.

```scala
test("Benchmark for CSV converter") {
  var numMalformedRecords = 0
  val N = 500 << 12
  val schema = StructType(
    StructField("a", StringType) ::
    StructField("b", StringType) ::
    StructField("c", StringType) ::
    StructField("d", StringType) :: Nil)

  val row = Array("1.0", "test", "2015-08-20 14:57:00", "FALSE")
  val data = spark.sparkContext.parallelize(List.fill(N)(row))
  val parser = CSVRelation.csvParser(schema, schema.fieldNames, CSVOptions())

  val benchmark = new Benchmark("CSV converter", N)
  benchmark.addCase("cast CSV string tokens", 10) { _ =>
    data.flatMap { recordTokens =>
      parser(recordTokens, numMalformedRecords)
    }.collect()
  }
  benchmark.run()
}
```

**Before**

```
CSV converter:                           Best/Avg Time(ms)    Rate(M/s)   Per Row(ns)   Relative
------------------------------------------------------------------------------------------------
cast CSV string tokens                        1061 / 1130          1.9         517.9       1.0X
```

**After**

```

[SPARK-18800][SQL] Correct the assert in UnsafeKVExternalSorter which ensures array size
## What changes were proposed in this pull request?

`UnsafeKVExternalSorter` uses `UnsafeInMemorySorter` to sort the records of `BytesToBytesMap` if it is given a map.

Currently we use the number of keys in `BytesToBytesMap` to determine if the array used for sort is enough or not. We has an assert that ensures the size of the array is enough: `map.numKeys() <= map.getArray().size() / 2`.

However, each record in the map takes two entries in the array, one is record pointer, another is key prefix. So the correct assert should be `map.numKeys() * 2 <= map.getArray().size() / 2`.

wangzhenhua 3cff816157 [SPARK-18911][SQL] Define CatalogStatistics to interact with metastore and convert it to Statistics in relations
## What changes were proposed in this pull request?

Statistics in LogicalPlan should use attributes to refer to columns rather than column names, because two columns from two relations can have the same column name. But CatalogTable doesn't have the concepts of attribute or broadcast hint in Statistics. Therefore, putting Statistics in CatalogTable is confusing.

We define a different statistic structure in CatalogTable, which is only responsible for interacting with metastore, and is converted to statistics in LogicalPlan when it is used.
