Reynold Xin 361ebc282b [SPARK-15543][SQL] Rename DefaultSources to make them more self-describing
## What changes were proposed in this pull request?
This patch renames various DefaultSources to make their names more self-describing. The choice of "DefaultSource" was from the days when we did not have a good way to specify short names.

They are now named:
- LibSVMFileFormat
- CSVFileFormat
- JdbcRelationProvider
- JsonFileFormat
- ParquetFileFormat
- TextFileFormat

Backward compatibility is maintained through aliasing.

## How was this patch tested?
Updated relevant test cases too.

Andrew Or ee682fe293 [SPARK-15534][SPARK-15535][SQL] Truncate table fixes
## What changes were proposed in this pull request?

Two changes:
- When things fail, `TRUNCATE TABLE` just returns nothing. Instead, we should throw exceptions.
- Remove `TRUNCATE TABLE ... COLUMN`, which was never supported by either Spark or Hive.

## How was this patch tested?
Jenkins.

Reynold Xin 4f27b8dd58 [SPARK-15436][SQL] Remove DescribeFunction and ShowFunctions
## What changes were proposed in this pull request?
This patch removes the last two commands defined in the catalyst module: DescribeFunction and ShowFunctions. They were unnecessary since the parser could just generate DescribeFunctionCommand and ShowFunctionsCommand directly.

## How was this patch tested?
Created a new SparkSqlParserSuite.

Parth Brahmbhatt 4acababcab [SPARK-15365][SQL] When table size statistics are not available from metastore, we should fallback to HDFS
## What changes were proposed in this pull request?
Currently if a table is used in join operation we rely on Metastore returned size to calculate if we can convert the operation to Broadcast join. This optimization only kicks in for table's that have the statistics available in metastore. Hive generally rolls over to HDFS if the statistics are not available directly from metastore and this seems like a reasonable choice to adopt given the optimization benefit of using broadcast joins.

## How was this patch tested?
I have executed queries locally to test.

## What changes were proposed in this pull request?

Xin Wu 01659bc50c [SPARK-15431][SQL] Support LIST FILE(s)|JAR(s) command natively
## What changes were proposed in this pull request?
Currently command `ADD FILE|JAR <filepath | jarpath>` is supported natively in SparkSQL. However, when this command is run, the file/jar is added to the resources that can not be looked up by `LIST FILE(s)|JAR(s)` command because the `LIST` command is passed to Hive command processor in Spark-SQL or simply not supported in Spark-shell. There is no way users can find out what files/jars are added to the spark context.
Refer to [Hive commands](https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Cli)

This PR is to support following commands:
`LIST (FILE[s] [filepath ...] | JAR[s] [jarfile ...])`

### For example:
##### LIST FILE(s)
```
scala> spark.sql("add file hdfs://bdavm009.svl.ibm.com:8020/tmp/test.txt")
res1: org.apache.spark.sql.DataFrame = []
scala> spark.sql("add file hdfs://bdavm009.svl.ibm.com:8020/tmp/test1.txt")
res2: org.apache.spark.sql.DataFrame = []

scala> spark.sql("list file hdfs://bdavm009.svl.ibm.com:8020/tmp/test1.txt").show(false)
+----------------------------------------------+
|result                                        |
+----------------------------------------------+
|hdfs://bdavm009.svl.ibm.com:8020/tmp/test1.txt|
+----------------------------------------------+

scala> spark.sql("list files").show(false)
+----------------------------------------------+
|result                                        |
+----------------------------------------------+
|hdfs://bdavm009.svl.ibm.com:8020/tmp/test1.txt|
|hdfs://bdavm009.svl.ibm.com:8020/tmp/test.txt |
+----------------------------------------------+
```

##### LIST JAR(s)
```
scala> spark.sql("add jar /Users/xinwu/spark/core/src/test/resources/TestUDTF.jar")
res9: org.apache.spark.sql.DataFrame = [result: int]

scala> spark.sql("list jar TestUDTF.jar").show(false)
+---------------------------------------------+
|result                                       |
+---------------------------------------------+
|spark://192.168.1.234:50131/jars/TestUDTF.jar|
+---------------------------------------------+

scala> spark.sql("list jars").show(false)
+---------------------------------------------+
|result                                       |

Andrew Or 2585d2b322 [SPARK-15279][SQL] Catch conflicting SerDe when creating table
## What changes were proposed in this pull request?

The user may do something like:
```
CREATE TABLE my_tab ROW FORMAT SERDE 'anything' STORED AS PARQUET
CREATE TABLE my_tab ROW FORMAT SERDE 'anything' STORED AS ... SERDE 'myserde'
CREATE TABLE my_tab ROW FORMAT DELIMITED ... STORED AS ORC
CREATE TABLE my_tab ROW FORMAT DELIMITED ... STORED AS ... SERDE 'myserde'
```
None of these should be allowed because the SerDe's conflict. As of this patch:
- `ROW FORMAT DELIMITED` is only compatible with `TEXTFILE`
- `ROW FORMAT SERDE` is only compatible with `TEXTFILE`, `RCFILE` and `SEQUENCEFILE`

Sameer Agarwal dafcb05c2e [SPARK-15425][SQL] Disallow cross joins by default
## What changes were proposed in this pull request?

In order to prevent users from inadvertently writing queries with cartesian joins, this patch introduces a new conf `spark.sql.crossJoin.enabled` (set to `false` by default) that if not set, results in a `SparkException` if the query contains one or more cartesian products.

## How was this patch tested?

Added a test to verify the new behavior in `JoinSuite`. Additionally, `SQLQuerySuite` and `SQLMetricsSuite` were modified to explicitly enable cartesian products.

Sean Zhong 6e02aec44b [SPARK-15334][SQL] HiveClient facade not compatible with Hive 0.12
## What changes were proposed in this pull request?

HiveClient facade is not compatible with Hive 0.12.

This PR Fixes the following compatibility issues:
1. `org.apache.spark.sql.hive.client.HiveClientImpl` use `AddPartitionDesc(db, table, ignoreIfExists)` to create partitions, however, Hive 0.12 doesn't have this constructor for `AddPartitionDesc`.
2. `HiveClientImpl` uses `PartitionDropOptions` when dropping partition, however, class `PartitionDropOptions` doesn't exist in Hive 0.12.
3. Hive 0.12 doesn't support adding permanent functions. It is not valid to call `org.apache.hadoop.hive.ql.metadata.Hive.createFunction`, `org.apache.hadoop.hive.ql.metadata.Hive.alterFunction`, and `org.apache.hadoop.hive.ql.metadata.Hive.alterFunction`
4. `org.apache.spark.sql.hive.client.VersionsSuite` doesn't have enough test coverage for different hive versions 0.12, 0.13, 0.14, 1.0.0, 1.1.0, 1.2.0.

Cheng Lian b674e67c22 [SPARK-14346][SQL] Native SHOW CREATE TABLE for Hive tables/views
## What changes were proposed in this pull request?

This is a follow-up of #12781. It adds native `SHOW CREATE TABLE` support for Hive tables and views. A new field `hasUnsupportedFeatures` is added to `CatalogTable` to indicate whether all table metadata retrieved from the concrete underlying external catalog (i.e. Hive metastore in this case) can be mapped to fields in `CatalogTable`. This flag is useful when the target Hive table contains structures that can't be handled by Spark SQL, e.g., skewed columns and storage handler, etc..

## How was this patch tested?

New test cases are added in `ShowCreateTableSuite` to do round-trip tests.

hyukjinkwon 8d05a7a98b [SPARK-10216][SQL] Avoid creating empty files during overwriting with group by query
## What changes were proposed in this pull request?

Currently, `INSERT INTO` with `GROUP BY` query tries to make at least 200 files (default value of `spark.sql.shuffle.partition`), which results in lots of empty files.

This PR makes it avoid creating empty files during overwriting into Hive table and in internal data sources  with group by query.

This checks whether the given partition has data in it or not and creates/writes file only when it actually has data.

hyukjinkwon 3ded5bc4db [SPARK-15267][SQL] Refactor options for JDBC and ORC data sources and change default compression for ORC
## What changes were proposed in this pull request?

Currently, Parquet, JSON and CSV data sources have a class for thier options, (`ParquetOptions`, `JSONOptions` and `CSVOptions`).

It is convenient to manage options for sources to gather options into a class. Currently, `JDBC`, `Text`, `libsvm` and `ORC` datasources do not have this class. This might be nicer if these options are in a unified format so that options can be added and

This PR refactors the options in Spark internal data sources adding new classes, `OrcOptions`, `TextOptions`, `JDBCOptions` and `LibSVMOptions`.

Also, this PR change the default compression codec for ORC from `NONE` to `SNAPPY`.

## How was this patch tested?

Existing tests should cover this for refactoring and unittests in `OrcHadoopFsRelationSuite` for changing the default compression codec for ORC.

Herman van Hovell bb1362eb3b [SPARK-10605][SQL] Create native collect_list/collect_set aggregates
## What changes were proposed in this pull request?
We currently use the Hive implementations for the collect_list/collect_set aggregate functions. This has a few major drawbacks: the use of HiveUDAF (which has quite a bit of overhead) and the lack of support for struct datatypes. This PR adds native implementation of these functions to Spark.

The size of the collected list/set may vary, this means we cannot use the fast, Tungsten, aggregation path to perform the aggregation, and that we fallback to the slower sort based path. Another big issue with these operators is that when the size of the collected list/set grows too large, we can start experiencing large GC pauzes and OOMEs.

This `collect*` aggregates implemented in this PR rely on the sort based aggregate path for correctness. They maintain their own internal buffer which holds the rows for one group at a time. The sortbased aggregation path is triggered by disabling `partialAggregation` for these aggregates (which is kinda funny); this technique is also employed in `org.apache.spark.sql.hiveHiveUDAFFunction`.

I have done some performance testing:
```scala
import org.apache.spark.sql.{Dataset, Row}

sql("create function collect_list2 as 'org.apache.hadoop.hive.ql.udf.generic.GenericUDAFCollectList'")

val df = range(0, 10000000).select($"id", (rand(213123L) * 100000).cast("int").as("grp"))
df.select(countDistinct($"grp")).show

def benchmark(name: String, plan: Dataset[Row], maxItr: Int = 5): Unit = {
   // Do not measure planning.
   plan1.queryExecution.executedPlan

   // Execute the plan a number of times and average the result.
   val start = System.nanoTime
   var i = 0
   while (i < maxItr) {
     plan.rdd.foreach(row => Unit)
     i += 1
   }
   val time = (System.nanoTime - start) / (maxItr * 1000000L)
   println(s"[$name] $maxItr iterations completed in an average time of $time ms.")
}

val plan1 = df.groupBy($"grp").agg(collect_list($"id"))
val plan2 = df.groupBy($"grp").agg(callUDF("collect_list2", $"id"))

benchmark("Spark collect_list", plan1)
...
> [Spark collect_list] 5 iterations completed in an average time of 3371 ms.

benchmark("Hive collect_list", plan2)
...
> [Hive collect_list] 5 iterations completed in an average time of 9109 ms.
```
Performance is improved by a factor 2-3.

## How was this patch tested?
Added tests to `DataFrameAggregateSuite`.

gatorsmile be617f3d06 [SPARK-14684][SPARK-15277][SQL] Partition Spec Validation in SessionCatalog and Checking Partition Spec Existence Before Dropping
#### What changes were proposed in this pull request?
~~Currently, multiple partitions are allowed to drop by using a single DDL command: Alter Table Drop Partition. However, the internal implementation could break atomicity. That means, we could just drop a subset of qualified partitions, if hitting an exception when dropping one of qualified partitions~~

~~This PR contains the following behavior changes:~~
~~- disallow dropping multiple partitions by a single command ~~
~~- allow users to input predicates in partition specification and issue a nicer error message if the predicate's comparison operator is not `=`.~~
~~- verify the partition spec in SessionCatalog. This can ensure each partition spec in `Drop Partition` does not correspond to multiple partitions.~~

This PR has two major parts:
- Verify the partition spec in SessionCatalog for fixing the following issue:
  ```scala
  sql(s"ALTER TABLE $externalTab DROP PARTITION (ds='2008-04-09', unknownCol='12')")
  ```
  Above example uses an invalid partition spec. Without this PR, we will drop all the partitions. The reason is Hive megastores getPartitions API returns all the partitions if we provide an invalid spec.

- Re-implemented the `dropPartitions` in `HiveClientImpl`. Now, we always check if all the user-specified partition specs exist before attempting to drop the partitions. Previously, we start drop the partition before completing checking the existence of all the partition specs. If any failure happened after we start to drop the partitions, we will log an error message to indicate which partitions have been dropped and which partitions have not been dropped.

#### How was this patch tested?

Cheng Lian f036dd7ce7 [SPARK-14346] SHOW CREATE TABLE for data source tables
## What changes were proposed in this pull request?

This PR adds native `SHOW CREATE TABLE` DDL command for data source tables. Support for Hive tables will be added in follow-up PR(s).

To show table creation DDL for data source tables created by CTAS statements, this PR also added partitioning and bucketing support for normal `CREATE TABLE ... USING ...` syntax.

## How was this patch tested?

(Please explain how this patch was tested. E.g. unit tests, integration tests, manual tests)

A new test suite `ShowCreateTableSuite` is added in sql/hive package to test the new feature.

Andrew Or f14c4ba001 [SPARK-15276][SQL] CREATE TABLE with LOCATION should imply EXTERNAL
## What changes were proposed in this pull request?

Before:
```sql
-- uses that location but issues a warning
CREATE TABLE my_tab LOCATION /some/path
-- deletes any existing data in the specified location
DROP TABLE my_tab
```

After:
```sql
-- uses that location but creates an EXTERNAL table instead
CREATE TABLE my_tab LOCATION /some/path
-- does not delete the data at /some/path
DROP TABLE my_tab
```

This patch essentially makes the `EXTERNAL` field optional. This is related to #13032.

## How was this patch tested?

New test in `DDLCommandSuite`.

Tathagata Das 81c68eceba [SPARK-15248][SQL] Make MetastoreFileCatalog consider directories from partition specs of a partitioned metastore table
Table partitions can be added with locations different from default warehouse location of a hive table.
`CREATE TABLE parquetTable (a int) PARTITIONED BY (b int) STORED AS parquet `
`ALTER TABLE parquetTable ADD PARTITION (b=1) LOCATION '/partition'`
Querying such a table throws error as the MetastoreFileCatalog does not list the added partition directory, it only lists the default base location.

xin Wu 427c20dd6d [SPARK-14933][SQL] Failed to create view out of a parquet or orc table
## What changes were proposed in this pull request?
#### Symptom
 If a table is created as parquet or ORC table with hive syntaxt DDL, such as
```SQL
create table t1 (c1 int, c2 string) stored as parquet
```
The following command will fail
```SQL
create view v1 as select * from t1
```
#### Root Cause
Currently, `HiveMetaStoreCatalog` converts Paruqet/Orc tables to `LogicalRelation` without giving any `tableIdentifier`. `SQLBuilder` expects the `LogicalRelation` to have an associated `tableIdentifier`. However, the `LogicalRelation` created earlier does not have such a `tableIdentifier`. Thus, `SQLBuilder.toSQL` can not recognize this logical plan and issue an exception.

This PR is to assign a `TableIdentifier` to the `LogicalRelation` when resolving parquet or orc tables in `HiveMetaStoreCatalog`.

## How was this patch tested?
testcases created and dev/run-tests is run.

gatorsmile 5c6b085578 [SPARK-14603][SQL] Verification of Metadata Operations by Session Catalog
Since we cannot really trust if the underlying external catalog can throw exceptions when there is an invalid metadata operation, let's do it in SessionCatalog.

- [X] The first step is to unify the error messages issued in Hive-specific Session Catalog and general Session Catalog.
- [X] The second step is to verify the inputs of metadata operations for partitioning-related operations. This is moved to a separate PR: https://github.com/apache/spark/pull/12801
- [X] The third step is to add database existence verification in `SessionCatalog`
- [X] The fourth step is to add table existence verification in `SessionCatalog`
- [X] The fifth step is to add function existence verification in `SessionCatalog`

Cheng Lian 8a12580d25 [SPARK-14127][SQL] "DESC <table>": Extracts schema information from table properties for data source tables
## What changes were proposed in this pull request?

This is a follow-up of #12934 and #12844. This PR adds a set of utility methods in `DDLUtils` to help extract schema information (user-defined schema, partition columns, and bucketing information) from data source table properties. These utility methods are then used in `DescribeTableCommand` to refine output for data source tables. Before this PR, the aforementioned schema information are only shown as table properties, which are hard to read.

This PR is to address a few existing issues in `EXPLAIN`:
- The `EXPLAIN` options `LOGICAL | FORMATTED | EXTENDED | CODEGEN` should not be 0 or more match. It should 0 or one match. Parser does not allow users to use more than one option in a single command.
- The option `LOGICAL` is not supported. Issue an exception when users specify this option in the command.
- The output of `EXPLAIN ` contains a weird empty line when the output of analyzed plan is empty. We should remove it. For example:

xin Wu 980bba0dcf [SPARK-15025][SQL] fix duplicate of PATH key in datasource table options
## What changes were proposed in this pull request?
The issue is that when the user provides the path option with uppercase "PATH" key, `options` contains `PATH` key and will get into the non-external case in the following code in `createDataSourceTables.scala`, where a new key "path" is created with a default path.
```
val optionsWithPath =
      if (!options.contains("path")) {
        isExternal = false
        options + ("path" -> sessionState.catalog.defaultTablePath(tableIdent))
      } else {
        options
      }
```
So before creating hive table, serdeInfo.parameters will contain both "PATH" and "path" keys and different directories. and Hive table's dataLocation contains the value of "path".

The fix in this PR is to convert `options` in the code above to `CaseInsensitiveMap` before checking for containing "path" key.

Ryan Blue 652bbb1bf6 [SPARK-14459][SQL] Detect relation partitioning and adjust the logical plan
## What changes were proposed in this pull request?

This detects a relation's partitioning and adds checks to the analyzer.
If an InsertIntoTable node has no partitioning, it is replaced by the
relation's partition scheme and input columns are correctly adjusted,
placing the partition columns at the end in partition order. If an
InsertIntoTable node has partitioning, it is checked against the table's
reported partitions.

These changes required adding a PartitionedRelation trait to the catalog
interface because Hive's MetastoreRelation doesn't extend
CatalogRelation.

This commit also includes a fix to InsertIntoTable's resolved logic,
which now detects that all expected columns are present, including
dynamic partition columns. Previously, the number of expected columns
was not checked and resolved was true if there were missing columns.

## How was this patch tested?

This adds new tests to the InsertIntoTableSuite that are fixed by this PR.

Tathagata Das f7b7ef4166 [SPARK-14997][SQL] Fixed FileCatalog to return correct set of files when there is no partitioning scheme in the given paths
## What changes were proposed in this pull request?
Lets says there are json files in the following directories structure
```
xyz/file0.json
xyz/subdir1/file1.json
xyz/subdir2/file2.json
xyz/subdir1/subsubdir1/file3.json
```
`sqlContext.read.json("xyz")` should read only file0.json according to behavior in Spark 1.6.1. However in current master, all the 4 files are read.

The fix is to make FileCatalog return only the children files of the given path if there is not partitioning detected (instead of all the recursive list of files).

hyukjinkwon fa928ff9a3 [SPARK-14962][SQL] Do not push down isnotnull/isnull on unsuportted types in ORC
## What changes were proposed in this pull request?

https://issues.apache.org/jira/browse/SPARK-14962

ORC filters were being pushed down for all types for both `IsNull` and `IsNotNull`.

This is apparently OK because both `IsNull` and `IsNotNull` do not take a type as an argument (Hive 1.2.x) during building filters (`SearchArgument`) in Spark-side but they do not filter correctly because stored statistics always produces `null` for not supported types (eg `ArrayType`) in ORC-side. So, it is always `true` for `IsNull` which ends up with always `false` for `IsNotNull`. (Please see [RecordReaderImpl.java#L296-L318](https://github.com/apache/hive/blob/branch-1.2/ql/src/java/org/apache/hadoop/hive/ql/io/orc/RecordReaderImpl.java#L296-L318)  and [RecordReaderImpl.java#L359-L365](https://github.com/apache/hive/blob/branch-1.2/ql/src/java/org/apache/hadoop/hive/ql/io/orc/RecordReaderImpl.java#L359-L365) in Hive 1.2)

This looks prevented in Hive 1.3.x >= by forcing to give a type ([`PredicateLeaf.Type`](e085b7e9bd/storage-api/src/java/org/apache/hadoop/hive/ql/io/sarg/PredicateLeaf.java (L50-L56))) when building a filter ([`SearchArgument`](26b5c7b56a/storage-api/src/java/org/apache/hadoop/hive/ql/io/sarg/SearchArgument.java (L260))) but Hive 1.2.x seems not doing this.

This PR prevents ORC filter creation for `IsNull` and `IsNotNull` on unsupported types. `OrcFilters` resembles `ParquetFilters`.

Tathagata Das 0fd3a47484 [SPARK-15103][SQL] Refactored FileCatalog class to allow StreamFileCatalog to infer partitioning
## What changes were proposed in this pull request?

File Stream Sink writes the list of written files in a metadata log. StreamFileCatalog reads the list of the files for processing. However StreamFileCatalog does not infer partitioning like HDFSFileCatalog.

This PR enables that by refactoring HDFSFileCatalog to create an abstract class PartitioningAwareFileCatalog, that has all the functionality to infer partitions from a list of leaf files.
- HDFSFileCatalog has been renamed to ListingFileCatalog and it extends PartitioningAwareFileCatalog by providing a list of leaf files from recursive directory scanning.
- StreamFileCatalog has been renamed to MetadataLogFileCatalog and it extends PartitioningAwareFileCatalog by providing a list of leaf files from the metadata log.
- The above two classes has been moved into their own files as they are not interfaces that should be in fileSourceInterfaces.scala.

## How was this patch tested?
- FileStreamSinkSuite was update to see if partitioning gets inferred, and on reading whether the partitions get pruned correctly based on the query.
- Other unit tests are unchanged and pass as expected.

Cheng Lian bc3760d405 [SPARK-14237][SQL] De-duplicate partition value appending logic in various buildReader() implementations
## What changes were proposed in this pull request?

Currently, various `FileFormat` data sources share approximately the same code for partition value appending. This PR tries to eliminate this duplication.

A new method `buildReaderWithPartitionValues()` is added to `FileFormat` with a default implementation that appends partition values to `InternalRow`s produced by the reader function returned by `buildReader()`.

Special data sources like Parquet, which implements partition value appending inside `buildReader()` because of the vectorized reader, and the Text data source, which doesn't support partitioning, override `buildReaderWithPartitionValues()` and simply delegate to `buildReader()`.

This PR brings two benefits:

1. Apparently, it de-duplicates partition value appending logic

2. Now the reader function returned by `buildReader()` is only required to produce `InternalRow`s rather than `UnsafeRow`s if the data source doesn't override `buildReaderWithPartitionValues()`.

   Because the safe-to-unsafe conversion is also performed while appending partition values. This makes 3rd-party data sources (e.g. spark-avro) easier to implement since they no longer need to access private APIs involving `UnsafeRow`.

## How was this patch tested?

Existing tests should do the work.

hyukjinkwon d7755cfd07 [SPARK-14917][SQL] Enable some ORC compressions tests for writing
## What changes were proposed in this pull request?

https://issues.apache.org/jira/browse/SPARK-14917

As it is described in the JIRA, it seems Hive 1.2.1 which Spark uses now supports snappy and none.

So, this PR enables some tests for writing ORC files with compression codes, `SNAPPY` and `NONE`.

## How was this patch tested?

Unittests in `OrcQuerySuite` and `sbt scalastyle`.

Andrew Or 66773eb8a5 [SPARK-15012][SQL] Simplify configuration API further
## What changes were proposed in this pull request?

1. Remove all the `spark.setConf` etc. Just expose `spark.conf`
2. Make `spark.conf` take in things set in the core `SparkConf` as well, otherwise users may get confused

This was done for both the Python and Scala APIs.

## How was this patch tested?
`SQLConfSuite`, python tests.

This one fixes the failed tests in #12787

Cheng Lian a04b1de5fa [SPARK-14981][SQL] Throws exception if DESC is specified for sorting columns
## What changes were proposed in this pull request?

Currently Spark SQL doesn't support sorting columns in descending order. However, the parser accepts the syntax and silently drops sorting directions. This PR fixes this by throwing an exception if `DESC` is specified as sorting direction of a sorting column.

## How was this patch tested?

A test case is added to test the invalid sorting order by checking exception message.

Wenchen Fan bf5496dbda [SPARK-14654][CORE] New accumulator API
## What changes were proposed in this pull request?

This PR introduces a new accumulator API  which is much simpler than before:

1. the type hierarchy is simplified, now we only have an `Accumulator` class
2. Combine `initialValue` and `zeroValue` concepts into just one concept: `zeroValue`
3. there in only one `register` method, the accumulator registration and cleanup registration are combined.
4. the `id`,`name` and `countFailedValues` are combined into an `AccumulatorMetadata`, and is provided during registration.

`SQLMetric` is a good example to show the simplicity of this new API.

What we break:

1. no `setValue` anymore. In the new API, the intermedia type can be different from the result type, it's very hard to implement a general `setValue`
2. accumulator can't be serialized before registered.

Problems need to be addressed in follow-ups:

1. with this new API, `AccumulatorInfo` doesn't make a lot of sense, the partial output is not partial updates, we need to expose the intermediate value.
2. `ExceptionFailure` should not carry the accumulator updates. Why do users care about accumulator updates for failed cases? It looks like we only use this feature to update the internal metrics, how about we sending a heartbeat to update internal metrics after the failure event?
3. the public event `SparkListenerTaskEnd` carries a `TaskMetrics`. Ideally this `TaskMetrics` don't need to carry external accumulators, as the only method of `TaskMetrics` that can access external accumulators is `private[spark]`. However, `SQLListener` use it to retrieve sql metrics.

Cheng Lian 24bea00047 [SPARK-14954] [SQL] Add PARTITION BY and BUCKET BY clause for data source CTAS syntax
Currently, we can only create persisted partitioned and/or bucketed data source tables using the Dataset API but not using SQL DDL. This PR implements the following syntax to add partitioning and bucketing support to the SQL DDL:

```
CREATE TABLE <table-name>
USING <provider> [OPTIONS (<key1> <value1>, <key2> <value2>, ...)]
[PARTITIONED BY (col1, col2, ...)]
[CLUSTERED BY (col1, col2, ...) [SORTED BY (col1, col2, ...)] INTO <n> BUCKETS]

We currently expose both Hadoop configuration and Spark SQL configuration in RuntimeConfig.

This way, there is a single interface (in Java/Scala/Python/SQL) for end-users.

As part of this patch, I also removed some config options deprecated in Spark 1.x.

## What changes were proposed in this pull request?

While the vectorized hash map in `TungstenAggregate` is currently supported for all primitive data types during partial aggregation, this patch only enables the hash map for a subset of cases that've been verified to show performance improvements on our benchmarks subject to an internal conf that sets an upper limit on the maximum length of the aggregate key/value schema. This list of supported use-cases should be expanded over time.

This is no new change in functionality so existing tests should suffice. Performance tests were done on TPCDS benchmarks.

Andrew Or 18c2c92580 [SPARK-14861][SQL] Replace internal usages of SQLContext with SparkSession
## What changes were proposed in this pull request?

In Spark 2.0, `SparkSession` is the new thing. Internally we should stop using `SQLContext` everywhere since that's supposed to be not the main user-facing API anymore.

In this patch I took care to not break any public APIs. The one place that's suspect is `o.a.s.ml.source.libsvm.DefaultSource`, but according to mengxr it's not supposed to be public so it's OK to change the underlying `FileFormat` trait.

**Reviewers**: This is a big patch that may be difficult to review but the changes are actually really straightforward. If you prefer I can break it up into a few smaller patches, but it will delay the progress of this issue a little.

## How was this patch tested?

No change in functionality intended.
