## What changes were proposed in this pull request?
Adding option in spark-submit to allow overriding the default IvySettings used to resolve artifacts as part of the Spark Packages functionality. This will allow all artifact resolution to go through a central managed repository, such as Nexus or Artifactory, where site admins can better approve and control what is used with Spark apps.
This change restructures the creation of the IvySettings object in two distinct ways. First, if the `spark.ivy.settings` option is not defined then `buildIvySettings` will create a default settings instance, as before, with defined repositories (Maven Central) included. Second, if the option is defined, the ivy settings file will be loaded from the given path and only repositories defined within will be used for artifact resolution.
## How was this patch tested?
Existing tests for default behaviour, Manual tests that load a ivysettings.xml file with local and Nexus repositories defined. Added new test to load a simple Ivy settings file with a local filesystem resolver.

## What changes were proposed in this pull request?
Currently we have two sets of statistics in LogicalPlan: a simple stats and a stats estimated by cbo, but the computing logic and naming are quite confusing, we need to unify these two sets of stats.
## How was this patch tested?
Just modify existing tests.

Closes#16529 from wzhfy/unifyStats.
## What changes were proposed in this pull request?
The analyzer rule that supports to query files directly will be added to `Analyzer.extendedResolutionRules` when SparkSession is created, according to the `spark.sql.runSQLOnFiles` flag. If the flag is off when we create `SparkSession`, this rule is not added and we can not query files directly even we turn on the flag later.
This PR fixes this bug by always adding that rule to `Analyzer.extendedResolutionRules`.

This does not look due to this problem so this PR does not fix it here.
Author: hyukjinkwon <gurwls223@gmail.com>
Closes#16451 from HyukjinKwon/all-path-resource-fixes.
## 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.
## How was this patch tested?
new tests in `HiveDDLSuite`
Author: Wenchen Fan <wenchen@databricks.com>
Closes#16487 from cloud-fan/hive-table.
## 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)`
## How was this patch tested?
existing tests.
Author: Wenchen Fan <wenchen@databricks.com>
Closes#16479 from cloud-fan/hive-writer.
## 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`.
## How was this patch tested?
new tests
Author: Wenchen Fan <wenchen@databricks.com>
Closes#16296 from cloud-fan/create-table.
## 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.
## How was this patch tested?
newly added regression tests
Author: Wenchen Fan <wenchen@databricks.com>
Closes#16460 from cloud-fan/append.
## What changes were proposed in this pull request?
There are many locations in the Spark repo where the same word occurs consecutively. Sometimes they are appropriately placed, but many times they are not. This PR removes the inappropriately duplicated words.
## How was this patch tested?
N/A since only docs or comments were updated.

Closes#16455 from neurons/np.structure_streaming_doc.
## What changes were proposed in this pull request?
Now all aggregation functions support partial aggregate, we can remove the `supportsPartual` flag in `AggregateFunction`
## How was this patch tested?
existing tests.
Author: Wenchen Fan <wenchen@databricks.com>
Closes#16461 from cloud-fan/partial.
### What changes were proposed in this pull request?
The data in the managed table should be deleted after table is dropped. However, if the partition location is not under the location of the partitioned table, it is not deleted as expected. Users can specify any location for the partition when they adding a partition.
This PR is to delete partition location when dropping managed partitioned tables stored in `InMemoryCatalog`.
### How was this patch tested?
Added test cases for both HiveExternalCatalog and InMemoryCatalog

Closes#16397 from HyukjinKwon/SPARK-18922-paths.
## 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.

### 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`

## 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.

## 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.

## What changes were proposed in this pull request?
This PR cleans up duplicated checking for file paths in implemented data sources and prevent to attempt to list twice in ORC data source.
https://github.com/apache/spark/pull/14585 handles a problem for the partition column name having `_` and the issue itself is resolved correctly. However, it seems the data sources implementing `FileFormat` are validating the paths duplicately. Assuming from the comment in `CSVFileFormat`, `// TODO: Move filtering.`, I guess we don't have to check this duplicately.
Currently, this seems being filtered in `PartitioningAwareFileIndex.shouldFilterOut` and`PartitioningAwareFileIndex.isDataPath`. So, `FileFormat.inferSchema` will always receive leaf files. For example, running to codes below:
``` scala
spark.range(10).withColumn("_locality_code", $"id").write.partitionBy("_locality_code").save("/tmp/parquet")
spark.read.parquet("/tmp/parquet")
```
gives the paths below without directories but just valid data files:
``` bash
/tmp/parquet/_col=0/part-r-00000-094a8efa-bece-4b50-b54c-7918d1f7b3f8.snappy.parquet
/tmp/parquet/_col=1/part-r-00000-094a8efa-bece-4b50-b54c-7918d1f7b3f8.snappy.parquet
/tmp/parquet/_col=2/part-r-00000-25de2b50-225a-4bcf-a2bc-9eb9ed407ef6.snappy.parquet
...
```
to `FileFormat.inferSchema`.

### What changes were proposed in this pull request?
Currently, we only have a SQL interface for recovering all the partitions in the directory of a table and update the catalog. `MSCK REPAIR TABLE` or `ALTER TABLE table RECOVER PARTITIONS`. (Actually, very hard for me to remember `MSCK` and have no clue what it means)
After the new "Scalable Partition Handling", the table repair becomes much more important for making visible the data in the created data source partitioned table.
Thus, this PR is to add it into the Catalog interface. After this PR, users can repair the table by
```Scala
spark.catalog.recoverPartitions("testTable")
```
### How was this patch tested?
Modified the existing test cases.

Closes#16356 from gatorsmile/repairTable.
## What changes were proposed in this pull request?
When we append data to an existing table with `DataFrameWriter.saveAsTable`, we will do various checks to make sure the appended data is consistent with the existing data.
However, we get the information of the existing table by matching the table relation, instead of looking at the table metadata. This is error-prone, e.g. we only check the number of columns for `HadoopFsRelation`, we forget to check bucketing, etc.
This PR refactors the error checking by looking at the metadata of the existing table, and fix several bugs:
* SPARK-18899: We forget to check if the specified bucketing matched the existing table, which may lead to a problematic table that has different bucketing in different data files.
* SPARK-18912: We forget to check the number of columns for non-file-based data source table
* SPARK-18913: We don't support append data to a table with special column names.

## What changes were proposed in this pull request?
It's weird that we use `Hive.getDatabase` to check the existence of a database, while Hive has a `databaseExists` interface.
What's worse, `Hive.getDatabase` will produce an error message if the database doesn't exist, which is annoying when we only want to check the database existence.
This PR fixes this and use `Hive.databaseExists` to check database existence.

As the scenario describe in [SPARK-18700](https://issues.apache.org/jira/browse/SPARK-18700), when cachedDataSourceTables invalided, the coming few queries will fetch all FileStatus in listLeafFiles function. In the condition of table has many partitions, these jobs will occupy much memory of driver finally may cause driver OOM.
In this patch, add StripedLock for each table's relation in cache not for the whole cachedDataSourceTables, each table's load cache operation protected by it.

The first 18 files are temporary. We do not drop it until the end of JVM termination. If JVM does not appropriately terminate, these temporary files/directories will not be dropped.
Only the last two files are needed, as shown below.

```
The temporary files/directories could accumulate a lot when we issue many inserts, since each insert generats at least six files. This could eat a lot of spaces and slow down the JVM termination. When the JVM does not terminates approprately, the files might not be dropped.
This PR is to drop the created staging files and temporary data files after each insert/CTAS.

Before hive 1.1, when inserting into a table, hive will create the staging directory under a common scratch directory. After the writing is finished, hive will simply empty the table directory and move the staging directory to it.
After hive 1.1, hive will create the staging directory under the table directory, and when moving staging directory to table directory, hive will still empty the table directory, but will exclude the staging directory there.
In `InsertIntoHiveTable`, we simply copy the code from hive 1.2, which means we will always create the staging directory under the table directory, no matter what the hive version is. This causes problems if the hive version is prior to 1.1, because the staging directory will be removed by hive when hive is trying to empty the table directory.
This PR copies the code from hive 0.13, so that we have 2 branches to create staging directory. If hive version is prior to 1.1, we'll go to the old style branch(i.e. create the staging directory under a common scratch directory), else, go to the new style branch(i.e. create the staging directory under the table directory)

Cloudera put `/var/run/cloudera-scm-agent/process/15000-hive-HIVEMETASTORE/hive-site.xml` as the configuration file for the Hive Metastore Server, where `hive.metastore.try.direct.sql=false`. But Spark isn't reading this configuration file and get default value `hive.metastore.try.direct.sql=true`. As mallman said, we should use `getMetaConf` method to obtain the original configuration from Hive Metastore Server. I have tested this method few times and the return value is always consistent with Hive Metastore Server.

Closes#16122 from wangyum/SPARK-18681.
The value of the "isSrcLocal" parameter passed to Hive's loadTable and
loadPartition methods needs to be set according to the user query (e.g.
"LOAD DATA LOCAL"), and not the current code that tries to guess what
it should be.
For existing versions of Hive the current behavior is probably ok, but
some recent changes in the Hive code changed the semantics slightly,
making code that sets "isSrcLocal" to "true" incorrectly to do the
wrong thing. It would end up moving the parent directory of the files
into the final location, instead of the file themselves, resulting
in a table that cannot be read.
I modified HiveCommandSuite so that existing "LOAD DATA" tests are run
both in local and non-local mode, since the semantics are slightly different.
The tests include a few new checks to make sure the semantics follow
what Hive describes in its documentation.
Tested with existing unit tests and also ran some Hive integration tests
with a version of Hive containing the changes that surfaced the problem.

Currently Spark answers the `SHOW PARTITIONS` command by fetching all of the table's partition metadata from the external catalog and constructing partition names therefrom. The Hive client has a `getPartitionNames` method which is many times faster for this purpose, with the performance improvement scaling with the number of partitions in a table.
To test the performance impact of this PR, I ran the `SHOW PARTITIONS` command on two Hive tables with large numbers of partitions. One table has ~17,800 partitions, and the other has ~95,000 partitions. For the purposes of this PR, I'll call the former table `table1` and the latter table `table2`. I ran 5 trials for each table with before-and-after versions of this PR. The results are as follows:
Spark at bdc8153, `SHOW PARTITIONS table1`, times in seconds:
7.901
3.983
4.018
4.331
4.261
Spark at bdc8153, `SHOW PARTITIONS table2`
(Timed out after 10 minutes with a `SocketTimeoutException`.)
Spark at this PR, `SHOW PARTITIONS table1`, times in seconds:
3.801
0.449
0.395
0.348
0.336
Spark at this PR, `SHOW PARTITIONS table2`, times in seconds:
5.184
1.63
1.474
1.519
1.41
Taking the best times from each trial, we get a 12x performance improvement for a table with ~17,800 partitions and at least a 426x improvement for a table with ~95,000 partitions. More significantly, the latter command doesn't even complete with the current code in master.
This is actually a patch we've been using in-house at VideoAmp since Spark 1.1. It's made all the difference in the practical usability of our largest tables. Even with tables with about 1,000 partitions there's a performance improvement of about 2-3x.
## How was this patch tested?
I added a unit test to `VersionsSuite` which tests that the Hive client's `getPartitionNames` method returns the correct number of partitions.

## What changes were proposed in this pull request?
Two bugs are addressed here
1. INSERT OVERWRITE TABLE sometime crashed when catalog partition management was enabled. This was because when dropping partitions after an overwrite operation, the Hive client will attempt to delete the partition files. If the entire partition directory was dropped, this would fail. The PR fixes this by adding a flag to control whether the Hive client should attempt to delete files.
2. The static partition spec for OVERWRITE TABLE was not correctly resolved to the case-sensitive original partition names. This resulted in the entire table being overwritten if you did not correctly capitalize your partition names.

## What changes were proposed in this pull request?
This replaces uses of `TextOutputFormat` with an `OutputStream`, which will either write directly to the filesystem or indirectly via a compressor (if so configured). This avoids intermediate buffering.
The inverse of this (reading directly from a stream) is necessary for streaming large JSON records (when `wholeFile` is enabled) so I wanted to keep the read and write paths symmetric.

## What changes were proposed in this pull request?
In Spark 2.1, we make Hive serde tables case-preserving by putting the table metadata in table properties, like what we did for data source table. However, we should not put table provider, as it will break forward compatibility. e.g. if we create a Hive serde table with Spark 2.1, using `sql("create table test stored as parquet as select 1")`, we will fail to read it with Spark 2.0, as Spark 2.0 mistakenly treat it as data source table because there is a `provider` entry in table properties.
Logically Hive serde table's provider is always hive, we don't need to store it in table properties, this PR removes it.
## How was this patch tested?
manually test the forward compatibility issue.

Closes#16080 from cloud-fan/hive.
## What changes were proposed in this pull request?
Due to confusion between URI vs paths, in certain cases we escape partition values too many times, which causes some Hive client operations to fail or write data to the wrong location. This PR fixes at least some of these cases.
To my understanding this is how values, filesystem paths, and URIs interact.
- Hive stores raw (unescaped) partition values that are returned to you directly when you call listPartitions.
- Internally, we convert these raw values to filesystem paths via `ExternalCatalogUtils.[un]escapePathName`.
- In some circumstances we store URIs instead of filesystem paths. When a path is converted to a URI via `path.toURI`, the escaped partition values are further URI-encoded. This means that to get a path back from a URI, you must call `new Path(new URI(uriTxt))` in order to decode the URI-encoded string.
- In `CatalogStorageFormat` we store URIs as strings. This makes it easy to forget to URI-decode the value before converting it into a path.
- Finally, the Hive client itself uses mostly Paths for representing locations, and only URIs occasionally.
In the future we should probably clean this up, perhaps by dropping use of URIs when unnecessary. We should also try fixing escaping for partition names as well as values, though names are unlikely to contain special characters.

## What changes were proposed in this pull request?
Spark SQL only has `StringType`, when reading hive table with varchar column, we will read that column as `StringType`. However, we still need to use varchar `ObjectInspector` to read varchar column in hive table, which means we need to know the actual column type at hive side.
In Spark 2.1, after https://github.com/apache/spark/pull/14363 , we parse hive type string to catalyst type, which means the actual column type at hive side is erased. Then we may use string `ObjectInspector` to read varchar column and fail.
This PR keeps the original hive column type string in the metadata of `StructField`, and use it when we convert it to a hive column.

Spark SQL supports Unicode characters for column names when specified within backticks(`). When the Hive support is enabled, the version of the Hive metastore must be higher than 0.12, See the JIRA: https://issues.apache.org/jira/browse/HIVE-6013 Hive metastore supports Unicode characters for column names since 0.13.
In Spark SQL, table comments, and view comments always allow Unicode characters without backticks.
BTW, a separate PR has been submitted for database and table name validation because we do not support Unicode characters in these two cases.

`AggregateFunction` currently implements `ImplicitCastInputTypes` (which enables implicit input type casting). There are actually quite a few situations in which we don't need this, or require more control over our input. A recent example is the aggregate for `CountMinSketch` which should only take string, binary or integral types inputs.
This PR removes `ImplicitCastInputTypes` from the `AggregateFunction` and makes a case-by-case decision on what kind of input validation we should use.

## What changes were proposed in this pull request?
This PR fixes a random OOM issue occurred while running `ObjectHashAggregateSuite`.
This issue can be steadily reproduced under the following conditions:
1. The aggregation must be evaluated using `ObjectHashAggregateExec`;
2. There must be an input column whose data type involves `ArrayType` (an input column of `MapType` may even cause SIGSEGV);
3. Sort-based aggregation fallback must be triggered during evaluation.
The root cause is that while falling back to sort-based aggregation, we must sort and feed already evaluated partial aggregation buffers living in the hash map to the sort-based aggregator using an external sorter. However, the underlying mutable byte buffer of `UnsafeRow`s produced by the iterator of the external sorter is reused and may get overwritten when the iterator steps forward. After the last entry is consumed, the byte buffer points to a block of uninitialized memory filled by `5a`. Therefore, while reading an `UnsafeArrayData` out of the `UnsafeRow`, `5a5a5a5a` is treated as array size and triggers a memory allocation for a ridiculously large array and immediately blows up the JVM with an OOM.
To fix this issue, we only need to add `.copy()` accordingly.
