We should upgrade to SBT 0.13.9, since this is a requirement in order to use SBT's new Maven-style resolution features (which will be done in a separate patch, because it's blocked by some binary compatibility issues in the POM reader plugin).

I also upgraded Scalastyle to version 0.8.0, which was necessary in order to fix a Scala 2.10.5 compatibility issue (see https://github.com/scalastyle/scalastyle/issues/156). The newer Scalastyle is slightly stricter about whitespace surrounding tokens, so I fixed the new style violations.

Closes #9867 from dskrvk/master.

This patch removes `spark.driver.allowMultipleContexts=true` from our test configuration. The multiple SparkContexts check was originally disabled because certain tests suites in SQL needed to create multiple contexts. As far as I know, this configuration change is no longer necessary, so we should remove it in order to make it easier to find test cleanup bugs.

This reverts commit e209fa27.

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.

This patch re-enables tests for the Docker JDBC data source. These tests were reverted in #4872 due to transitive dependency conflicts introduced by the `docker-client` library. This patch should avoid those problems by using a version of `docker-client` which shades its transitive dependencies and by performing some build-magic to work around problems with that shaded JAR.

In addition, I significantly refactored the tests to simplify the setup and teardown code and to fix several Docker networking issues which caused problems when running in `boot2docker`.

- 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.

Finish deprecating Bagel; remove reference to nonexistent example

Author: Sean Owen <sowen@cloudera.com>

Closes #8731 from srowen/SPARK-10222.

This change aims at speeding up the dev cycle a little bit, by making
sure that all tests behave the same w.r.t. where the code to be tested
is loaded from. Namely, that means that tests don't rely on the assembly
anymore, rather loading all needed classes from the build directories.

The main change is to make sure all build directories (classes and test-classes)
are added to the classpath of child processes when running tests.

YarnClusterSuite required some custom code since the executors are run
differently (i.e. not through the launcher library, like standalone and
Mesos do).

I also found a couple of tests that could leak a SparkContext on failure,
and added code to handle those.

With this patch, it's possible to run the following command from a clean
source directory and have all tests pass:

  mvn -Pyarn -Phadoop-2.4 -Phive-thriftserver install

pwendell mentioned that MapR should use `hadoop-provided` now, and indeed the new build script does not produce `mapr3`/`mapr4` artifacts anymore. Hence the action seems to be to remove the profiles, which are now not used.

Closes #8338 from srowen/SPARK-6196.

https://issues.apache.org/jira/browse/SPARK-9439

In general, Yarn apps should be robust to NodeManager restarts.  However, if you run spark with the external shuffle service on, after a NM restart all shuffles fail, b/c the shuffle service has lost some state with info on each executor.  (Note the shuffle data is perfectly fine on disk across a NM restart, the problem is we've lost the small bit of state that lets us *find* those files.)

The solution proposed here is that the external shuffle service can write out its state to leveldb (backed by a local file) every time an executor is added.  When running with yarn, that file is in the NM's local dir.  Whenever the service is started, it looks for that file, and if it exists, it reads the file and re-registers all executors there.

Nothing is changed in non-yarn modes with this patch.  The service is not given a place to save the state to, so it operates the same as before.  This should make it easy to update other cluster managers as well, by just supplying the right file & the equivalent of yarn's `initializeApplication` -- I'm not familiar enough with those modes to know how to do that.

[SPARK-9974] [BUILD] [SQL] Makes sure com.twitter:parquet-hadoop-bundle:1.6.0 is in SBT assembly jar

PR #7967 enables Spark SQL to persist Parquet tables in Hive compatible format when possible. One of the consequence is that, we have to set input/output classes to `MapredParquetInputFormat`/`MapredParquetOutputFormat`, which rely on com.twitter:parquet-hadoop:1.6.0 bundled with Hive 1.2.1.

When loading such a table in Spark SQL, `o.a.h.h.ql.metadata.Table` first loads these input/output format classes, and thus classes in com.twitter:parquet-hadoop:1.6.0.  However, the scope of this dependency is defined as "runtime", and is not packaged into Spark assembly jar.  This results in a `ClassNotFoundException`.

This issue can be worked around by asking users to add parquet-hadoop 1.6.0 via the `--driver-class-path` option.  However, considering Maven build is immune to this problem, I feel it can be confusing and inconvenient for users.

So this PR fixes this issue by changing scope of parquet-hadoop 1.6.0 to "compile".

Author: Cheng Lian <lian@databricks.com>

Closes #8198 from liancheng/spark-9974/bundle-parquet-1.6.0.

The REST server is not actually used in most tests and so we can disable it. It is a source of flakiness because it tries to bind to a specific port in vain. There was also some code that avoided the shuffle service in tests. This is actually not necessary because the shuffle service is already off by default.

Update to shade plugin 2.4.1, which removes the need for the dependency-reduced-POM workaround and the 'release' profile. Fix management of shade plugin version so children inherit it; bump assembly plugin version while here

See https://issues.apache.org/jira/browse/SPARK-8819

1917729 [Zhang, Liye] SPARK-9212 upgrade Netty version to 4.0.29.Final

These commits address a few minor issues in the Scala cross-version support in the build:

  1. Correct two missing `${scala.binary.version}` pom file substitutions.
  2. Don't update `scala.binary.version` in parent POM. This property is set through profiles.
  3. Update the source of the generated scaladocs in `docs/_plugins/copy_api_dirs.rb`.
  4. Factor common code out of `dev/change-version-to-*.sh` and add some validation. We also test `sed` to see if it's GNU sed and try `gsed` as an alternative if not. This prevents the script from running with a non-GNU sed.

This is my original work and I license this work to the Spark project under the Apache License.

We are running Spark 1.4.0 in production and ran into problems because after a network hiccup (which happens often in our current environment) no more metrics were reported to graphite leaving us blindfolded about the current state of our spark applications. [This problem](https://github.com/dropwizard/metrics/commit/70559816f1fc3a0a0122b5263d5478ff07396991) was fixed in the current version of the metrics library. We run spark with this change  in production now and have seen no problems. We also had a look at the commit history since 3.1.0 and did not detect any potentially  incompatible changes but many fixes which could potentially help other users as well.

94b80ae [Hari Shreedharan] [SPARK-8533][Streaming] Upgrade Flume to 1.6.0

This PR removes most of the code in the Spark REPL for Scala 2.11 and leaves just a couple of overridden methods in `SparkILoop` in order to:

- change welcome message
- restrict available commands (like `:power`)
- initialize Spark context

The two codebases have diverged and it's extremely hard to backport fixes from the upstream REPL. This somewhat radical step is absolutely necessary in order to fix other REPL tickets (like SPARK-8013 - Hive Thrift server for 2.11). BTW, the Scala REPL has fixed the serialization-unfriendly wrappers thanks to ScrapCodes's work in [#4522](https://github.com/scala/scala/pull/4522)

All tests pass and I tried the `spark-shell` on our Mesos cluster with some simple jobs (including with additional jars), everything looked good.

As soon as Scala 2.11.7 is out we need to upgrade and get a shaded `jline` dependency, clearing the way for SPARK-8013.
