Xin Ren 21a6dd2aef [SPARK-16535][BUILD] In pom.xml, remove groupId which is redundant definition and inherited from the parent
https://issues.apache.org/jira/browse/SPARK-16535

## What changes were proposed in this pull request?

When I scan through the pom.xml of sub projects, I found this warning as below and attached screenshot
```
Definition of groupId is redundant, because it's inherited from the parent
```

I've tried to remove some of the lines with groupId definition, and the build on my local machine is still ok.
```
<groupId>org.apache.spark</groupId>
```
As I just find now `<maven.version>3.3.9</maven.version>` is being used in Spark 2.x, and Maven-3 supports versionless parent elements: Maven 3 will remove the need to specify the parent version in sub modules. THIS is great (in Maven 3.1).

## What changes were proposed in this pull request?

(See https://github.com/apache/spark/pull/12416 where most of this was already reviewed and committed; this is just the module structure and move part. This change does not move the annotations into test scope, which was the apparently problem last time.)

Josh Rosen 649335d6c1 [SPARK-14797][BUILD] Spark SQL POM should not hardcode spark-sketch_2.11 dep.
Spark SQL's POM hardcodes a dependency on `spark-sketch_2.11`, which causes Scala 2.10 builds to include the `_2.11` dependency. This is harmless since `spark-sketch` is a pure-Java module (see #12334 for a discussion of dropping the Scala version suffixes from these modules' artifactIds), but it's confusing to people looking at the published POMs.

This patch fixes this by using `${scala.binary.version}` to substitute the correct suffix, and also adds a set of Maven Enforcer rules to ensure that `_2.11` artifacts are not used in 2.10 builds (and vice-versa).

hyukjinkwon 725b860e2b [SPARK-14103][SQL] Parse unescaped quotes in CSV data source.
## What changes were proposed in this pull request?

This PR resolves the problem during parsing unescaped quotes in input data. For example, currently the data below:

```
"a"b,ccc,ddd
e,f,g
```

produces a data below:

- **Before**

```bash
["a"b,ccc,ddd[\n]e,f,g]  <- as a value.
```

- **After**

```bash
["a"b], [ccc], [ddd]
[e], [f], [g]
```

This PR bumps up the Univocity parser's version. This was fixed in `2.0.2`, https://github.com/uniVocity/univocity-parsers/issues/60.

## How was this patch tested?

Unit tests in `CSVSuite` and `sbt/sbt scalastyle`.

Josh Rosen 289373b28c [SPARK-6363][BUILD] Make Scala 2.11 the default Scala version
This patch changes Spark's build to make Scala 2.11 the default Scala version. To be clear, this does not mean that Spark will stop supporting Scala 2.10: users will still be able to compile Spark for Scala 2.10 by following the instructions on the "Building Spark" page; however, it does mean that Scala 2.11 will be the default Scala version used by our CI builds (including pull request builds).

The Scala 2.11 compiler is faster than 2.10, so I think we'll be able to look forward to a slight speedup in our CI builds (it looks like it's about 2X faster for the Maven compile-only builds, for instance).

After this patch is merged, I'll update Jenkins to add new compile-only jobs to ensure that Scala 2.10 compilation doesn't break.

Hossein 5f83c6991c [SPARK-12833][SQL] Initial import of spark-csv
CSV is the most common data format in the "small data" world. It is often the first format people want to try when they see Spark on a single node. Having to rely on a 3rd party component for this leads to poor user experience for new users. This PR merges the popular spark-csv data source package (https://github.com/databricks/spark-csv) with SparkSQL.

This is a first PR to bring the functionality to spark 2.0 master. We will complete items outlines in the design document (see JIRA attachment) in follow up pull requests.

Josh Rosen 529a1d3380 [SPARK-6152] Use shaded ASM5 to support closure cleaning of Java 8 compiled classes
This patch modifies Spark's closure cleaner (and a few other places) to use ASM 5, which is necessary in order to support cleaning of closures that were compiled by Java 8.

In order to avoid ASM dependency conflicts, Spark excludes ASM from all of its dependencies and uses a shaded version of ASM 4 that comes from `reflectasm` (see [SPARK-782](https://issues.apache.org/jira/browse/SPARK-782) and #232). This patch updates Spark to use a shaded version of ASM 5.0.4 that was published by the Apache XBean project; the POM used to create the shaded artifact can be found at https://github.com/apache/geronimo-xbean/blob/xbean-4.4/xbean-asm5-shaded/pom.xml.

http://movingfulcrum.tumblr.com/post/80826553604/asm-framework-50-the-missing-migration-guide was a useful resource while upgrading the code to use the new ASM5 opcodes.

I also added a new regression tests in the `java8-tests` subproject; the existing tests were insufficient to catch this bug, which only affected Scala 2.11 user code which was compiled targeting Java 8.

Marcelo Vanzin 8abef21dac [SPARK-10300] [BUILD] [TESTS] Add support for test tags in run-tests.py.
This change does two things:

- tag a few tests and adds the mechanism in the build to be able to disable those tags,
  both in maven and sbt, for both junit and scalatest suites.
- add some logic to run-tests.py to disable some tags depending on what files have
  changed; that's used to disable expensive tests when a module hasn't explicitly
  been changed, to speed up testing for changes that don't directly affect those
  modules.

Reynold Xin 2e981b7bfa [SPARK-9531] [SQL] UnsafeFixedWidthAggregationMap.destructAndCreateExternalSorter
This pull request adds a destructAndCreateExternalSorter method to UnsafeFixedWidthAggregationMap. The new method does the following:

1. Creates a new external sorter UnsafeKVExternalSorter
2. Adds all the data into an in-memory sorter, sorts them
3. Spills the sorted in-memory data to disk

This method can be used to fallback to sort-based aggregation when under memory pressure.

The pull request also includes accounting fixes from JoshRosen.

TODOs (that can be done in follow-up PRs)
- [x] Address Josh's feedbacks from #7849
- [x] More documentation and test cases
- [x] Make sure we are doing memory accounting correctly with test cases (e.g. did we release the memory in BytesToBytesMap twice?)

Cheng Lian 2d45571fcb [SPARK-8959] [SQL] [HOTFIX] Removes parquet-thrift and libthrift dependencies
These two dependencies were introduced in #7231 to help testing Parquet compatibility with `parquet-thrift`. However, they somehow crash the Scala compiler in Maven builds.

This PR fixes this issue by:

1. Removing these two dependencies, and
2. Instead of generating the testing Parquet file programmatically, checking in an actual testing Parquet file generated by `parquet-thrift` as a test resource.

This is just a quick fix to bring back Maven builds. Need to figure out the root case as binary Parquet files are harder to maintain.

Cheng Lian 4ffc27caaf [SPARK-6123] [SPARK-6775] [SPARK-6776] [SQL] Refactors Parquet read path for interoperability and backwards-compatibility
This PR is a follow-up of #6617 and is part of [SPARK-6774] [2], which aims to ensure interoperability and backwards-compatibility for Spark SQL Parquet support.  And this one fixes the read path.  Now Spark SQL is expected to be able to read legacy Parquet data files generated by most (if not all) common libraries/tools like parquet-thrift, parquet-avro, and parquet-hive. However, we still need to refactor the write path to write standard Parquet LISTs and MAPs ([SPARK-8848] [4]).

### Major changes

1. `CatalystConverter` class hierarchy refactoring

   - Replaces `CatalystConverter` trait with a much simpler `ParentContainerUpdater`.

     Now instead of extending the original `CatalystConverter` trait, every converter class accepts an updater which is responsible for propagating the converted value to some parent container. For example, appending array elements to a parent array buffer, appending a key-value pairs to a parent mutable map, or setting a converted value to some specific field of a parent row. Root converter doesn't have a parent and thus uses a `NoopUpdater`.

     This simplifies the design since converters don't need to care about details of their parent converters anymore.

   - Unifies `CatalystRootConverter`, `CatalystGroupConverter` and `CatalystPrimitiveRowConverter` into `CatalystRowConverter`

     Specifically, now all row objects are represented by `SpecificMutableRow` during conversion.

   - Refactors `CatalystArrayConverter`, and removes `CatalystArrayContainsNullConverter` and `CatalystNativeArrayConverter`

     `CatalystNativeArrayConverter` was probably designed with the intention of avoiding boxing costs. However, the way it uses Scala generics actually doesn't achieve this goal.

     The new `CatalystArrayConverter` handles both nullable and non-nullable array elements in a consistent way.

   - Implements backwards-compatibility rules in `CatalystArrayConverter`

     When Parquet records are being converted, schema of Parquet files should have already been verified. So we only need to care about the structure rather than field names in the Parquet schema. Since all map objects represented in legacy systems have the same structure as the standard one (see [backwards-compatibility rules for MAP] [1]), we only need to deal with LIST (namely array) in `CatalystArrayConverter`.

2. Requested columns handling

   When specifying requested columns in `RowReadSupport`, we used to use a Parquet `MessageType` converted from a Catalyst `StructType` which contains all requested columns.  This is not preferable when taking compatibility and interoperability into consideration.  Because the actual Parquet file may have different physical structure from the converted schema.

   In this PR, the schema for requested columns is constructed using the following method:

   - For a column that exists in the target Parquet file, we extract the column type by name from the full file schema, and construct a single-field `MessageType` for that column.
   - For a column that doesn't exist in the target Parquet file, we create a single-field `StructType` and convert it to a `MessageType` using `CatalystSchemaConverter`.
   - Unions all single-field `MessageType`s into a full schema containing all requested fields

   With this change, we also fix [SPARK-6123] [3] by validating the global schema against each individual Parquet part-files.

### Testing

This PR also adds compatibility tests for parquet-avro, parquet-thrift, and parquet-hive. Please refer to `README.md` under `sql/core/src/test` for more information about these tests. To avoid build time code generation and adding extra complexity to the build system, Java code generated from testing Thrift schema and Avro IDL is also checked in.

Cheng Lian 76b472f12a [SPARK-6136] [SQL] Removed JDBC integration tests which depends on docker-client
Integration test suites in the JDBC data source (`MySQLIntegration` and `PostgresIntegration`) depend on docker-client 2.7.5, which transitively depends on Guava 17.0. Unfortunately, Guava 17.0 is causing test runtime binary compatibility issues when Spark is compiled against Hive 0.12.0, or Hadoop 2.4.

Considering `MySQLIntegration` and `PostgresIntegration` are ignored right now, I'd suggest moving them from the Spark project to the [Spark integration tests] [1] project. This PR removes both the JDBC data source integration tests and the docker-client test dependency.

Tor Myklebust 8f471a66db [SPARK-5472][SQL] A JDBC data source for Spark SQL.
This pull request contains a Spark SQL data source that can pull data from, and can put data into, a JDBC database.

I have tested both read and write support with H2, MySQL, and Postgres.  It would surprise me if both read and write support worked flawlessly out-of-the-box for any other database; different databases have different names for different JDBC data types and different meanings for SQL types with the same name.  However, this code is designed (see `DriverQuirks.scala`) to make it *relatively* painless to add support for another database by augmenting the type mapping contained in this PR.

- Create new profiles for other libraries / services that might be provided by the infrastructure
- Simplify and fix the poms so that the profiles are only activated while building assemblies.
- Fix tests so that they're able to run when the profiles are activated
- Add a new env variable to be used by distributions that use these profiles to provide the runtime
  classpath for Spark jobs and daemons.

Sean Owen 4cba6eb420 SPARK-4159 [CORE] Maven build doesn't run JUnit test suites
This PR:

- Reenables `surefire`, and copies config from `scalatest` (which is itself an old fork of `surefire`, so similar)
- Tells `surefire` to test only Java tests
- Enables `surefire` and `scalatest` for all children, and in turn eliminates some duplication.

For me this causes the Scala and Java tests to be run once each, it seems, as desired. It doesn't affect the SBT build but works for Maven. I still need to verify that all of the Scala tests and Java tests are being run.

Sean Owen 6ab96a6fd0 SPARK-2749 [BUILD]. Spark SQL Java tests aren't compiling in Jenkins' Maven builds; missing junit:junit dep
The Maven-based builds in the build matrix have been failing for a few days:

https://amplab.cs.berkeley.edu/jenkins/view/Spark/

On inspection, it looks like the Spark SQL Java tests don't compile:

https://amplab.cs.berkeley.edu/jenkins/view/Spark/job/Spark-Master-Maven-pre-YARN/hadoop.version=1.0.4,label=centos/244/consoleFull

I confirmed it by repeating the command vs master:

`mvn -Dhadoop.version=1.0.4 -Dlabel=centos -DskipTests clean package`

The problem is that this module doesn't depend on JUnit. In fact, none of the modules do, but `com.novocode:junit-interface` (the SBT-JUnit bridge) pulls it in, in most places. However this module doesn't depend on `com.novocode:junit-interface`

Adding the `junit:junit` dependency fixes the compile problem. In fact, the other modules with Java tests should probably depend on it explicitly instead of happening to get it via `com.novocode:junit-interface`, since that is a bit SBT/Scala-specific (and I am not even sure it's needed).

Cheng Lian a7a9d14479 [SPARK-2410][SQL] Merging Hive Thrift/JDBC server (with Maven profile fix)
JIRA issue: [SPARK-2410](https://issues.apache.org/jira/browse/SPARK-2410)

Another try for #1399 & #1600. Those two PR breaks Jenkins builds because we made a separate profile `hive-thriftserver` in sub-project `assembly`, but the `hive-thriftserver` module is defined outside the `hive-thriftserver` profile. Thus every time a pull request that doesn't touch SQL code will also execute test suites defined in `hive-thriftserver`, but tests fail because related .class files are not included in the assembly jar.

In the most recent commit, module `hive-thriftserver` is moved into its own profile to fix this problem. All previous commits are squashed for clarity.

TODO

- [x] Use `spark-submit` to launch the server, the CLI and beeline
- [x] Migration guideline draft for Shark users

----

Hit by a bug in `SparkSubmitArguments` while working on this PR: all application options that are recognized by `SparkSubmitArguments` are stolen as `SparkSubmit` options. For example:

```bash
$ spark-submit --class org.apache.hive.beeline.BeeLine spark-internal --help
```

This actually shows usage information of `SparkSubmit` rather than `BeeLine`.

~~Fixed this bug here since the `spark-internal` related stuff also touches `SparkSubmitArguments` and I'd like to avoid conflict.~~

**UPDATE** The bug mentioned above is now tracked by [SPARK-2678](https://issues.apache.org/jira/browse/SPARK-2678). Decided to revert changes to this bug since it involves more subtle considerations and worth a separate PR.
