* [SQL] Fixes caching related JoinSuite failureCheng Lian2014-10-272-57/+64
| | | | | | | | | | | | PR #2860 refines in-memory table statistics and enables broader broadcasted hash join optimization for in-memory tables. This makes `JoinSuite` fail when some test suite caches test table `testData` and gets executed before `JoinSuite`. Because expected `ShuffledHashJoin`s are optimized to `BroadcastedHashJoin` according to collected in-memory table statistics. This PR fixes this issue by clearing the cache before testing join operator selection. A separate test case is also added to test broadcasted hash join operator selection.

* SPARK-2621. Update task InputMetrics incrementallySandy Ryza2014-10-276-21/+170
| | | | | | | | | | | | | | | | | | The patch takes advantage an API provided in Hadoop 2.5 that allows getting accurate data on Hadoop FileSystem bytes read. It eliminates the old method, which naively accepts the split size as the input bytes. An impact of this change will be that input metrics go away when using against Hadoop versions earlier thatn 2.5. I can add this back in, but my opinion is that no metrics are better than inaccurate metrics. This is difficult to write a test for because we don't usually build against a version of Hadoop that contains the function we need. I've tested it manually on a pseudo-distributed cluster.

* [SPARK-3616] Add basic Selenium tests to WebUISuiteJosh Rosen2014-10-268-9/+135
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds Selenium tests for Spark's web UI. To avoid adding extra dependencies to the test environment, the tests use Selenium's HtmlUnitDriver, which is pure-Java, instead of, say, ChromeDriver. I added new tests to try to reproduce a few UI bugs reported on JIRA, namely SPARK-3021, SPARK-2105, and SPARK-2527. I wasn't able to reproduce these bugs; I suspect that the older ones might have been fixed by other patches. In order to use HtmlUnitDriver, I added an explicit dependency on the org.apache.httpcomponents version of httpclient in order to prevent jets3t's older version from taking precedence on the classpath. I also upgraded ScalaTest to 2.2.1.

* [SPARK-2321] Stable pull-based progress / status APIJosh Rosen2014-10-2521-134/+588
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This pull request is a first step towards the implementation of a stable, pull-based progress / status API for Spark (see [SPARK-2321](https://issues.apache.org/jira/browse/SPARK-2321)). For now, I'd like to discuss the basic implementation, API names, and overall interface design. Once we arrive at a good design, I'll go back and add additional methods to expose more information via these API. #### Design goals: - Pull-based API - Usable from Java / Scala / Python (eventually, likely with a wrapper) - Can be extended to expose more information without introducing binary incompatibilities. - Returns immutable objects. - Don't leak any implementation details, preserving our freedom to change the implementation. #### Implementation: - Add public methods (`getJobInfo`, `getStageInfo`) to SparkContext to allow status / progress information to be retrieved. - Add public interfaces (`SparkJobInfo`, `SparkStageInfo`) for our API return values. These interfaces consist entirely of Java-style getter methods. The interfaces are currently implemented in Java. I decided to explicitly separate the interface from its implementation (`SparkJobInfoImpl`, `SparkStageInfoImpl`) in order to prevent users from constructing these responses themselves. -Allow an existing JobProgressListener to be used when constructing a live SparkUI. This allows us to re-use this listeners in the implementation of this status API. There are a few reasons why this listener re-use makes sense: - The status API and web UI are guaranteed to show consistent information. - These listeners are already well-tested. - The same garbage-collection / information retention configurations can apply to both this API and the web UI. - Extend JobProgressListener to maintain `jobId -> Job` and `stageId -> Stage` mappings. The progress API methods are implemented in a separate trait that's mixed into SparkContext. This helps to avoid SparkContext.scala from becoming larger and more difficult to read.

This patch fixes this by adding a utility method that re-wraps any uncaught exceptions in IOException (unless they are already instances of IOException).

It maybe result in huge latency. In my case, it result in 20 seconds latency to download dependent jars(size about 17M) when I lunched 32 executors in every host(total 4 hosts).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of the effort to avoid data loss on Spark Streaming driver failure, we want to implement a write ahead log that can write received data to HDFS. This allows the received data to be persist across driver failures. So when the streaming driver is restarted, it can find and reprocess all the data that were received but not processed. This was primarily implemented by @harishreedharan. This is still WIP, as he is going to improve the unitests by using HDFS mini cluster.

* [SPARK-2706][SQL] Enable Spark to support Hive 0.13Zhan Zhang2014-10-2419-63/+406
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given that a lot of users are trying to use hive 0.13 in spark, and the incompatibility between hive-0.12 and hive-0.13 on the API level I want to propose following approach, which has no or minimum impact on existing hive-0.12 support, but be able to jumpstart the development of hive-0.13 and future version support. Approach: Introduce “hive-version” property, and manipulate pom.xml files to support different hive version at compiling time through shim layer, e.g., hive-0.12.0 and hive-0.13.1. More specifically, 1. For each different hive version, there is a very light layer of shim code to handle API differences, sitting in sql/hive/hive-version, e.g., sql/hive/v0.12.0 or sql/hive/v0.13.1 2. Add a new profile hive-default active by default, which picks up all existing configuration and hive-0.12.0 shim (v0.12.0) if no hive.version is specified. 3. If user specifies different version (currently only 0.13.1 by -Dhive.version = 0.13.1), hive-versions profile will be activated, which pick up hive-version specific shim layer and configuration, mainly the hive jars and hive-version shim, e.g., v0.13.1. 4. With this approach, nothing is changed with current hive-0.12 support. No change by default: sbt/sbt -Phive For example: sbt/sbt -Phive -Pyarn -Phadoop-2.4 -Dhadoop.version=2.4.0 assembly To enable hive-0.13: sbt/sbt -Dhive.version=0.13.1 For example: sbt/sbt -Dhive.version=0.13.1 -Pyarn -Phadoop-2.4 -Dhadoop.version=2.4.0 assembly Note that in hive-0.13, hive-thriftserver is not enabled, which should be fixed by other Jira, and we don’t need -Phive with -Dhive.version in building (probably we should use -Phive -Dhive.version=xxx instead after thrift server is also supported in hive-0.13.1).

* [SPARK-4050][SQL] Fix caching of temporary tables with projections.Michael Armbrust2014-10-244-12/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously cached data was found by `sameResult` plan matching on optimized plans. This technique however fails to locate the cached data when a temporary table with a projection is queried with a further reduced projection. The failure is due to the fact that optimization will collapse the projections, producing a plan that no longer produces the sameResult as the cached data (though the cached data still subsumes the desired data). For example consider the following previously failing test case. ```scala sql("CACHE TABLE tempTable AS SELECT key FROM testData") assertCached(sql("SELECT COUNT(*) FROM tempTable")) ``` In this PR I change the matching to occur after analysis instead of optimization, so that in the case of temporary tables, the plans will always match. I think this should work generally, however, this error does raise questions about the need to do more thorough subsumption checking when locating cached data. Another question is what sort of semantics we want to provide when uncaching data from temporary tables. For example consider the following sequence of commands: ```scala testData.select('key).registerTempTable("tempTable1") testData.select('key).registerTempTable("tempTable2") cacheTable("tempTable1") // This obviously works. assertCached(sql("SELECT COUNT(*) FROM tempTable1")) // It seems good that this works ... assertCached(sql("SELECT COUNT(*) FROM tempTable2")) // ... but is this valid? uncacheTable("tempTable2") // Should this still be cached? assertCached(sql("SELECT COUNT(*) FROM tempTable1"), 0) ``` Author: Michael Armbrust <michael@databricks.com> Closes #2912 from marmbrus/cachingBug and squashes the following commits: 9c822d4 [Michael Armbrust] remove commented out code 5c72fb7 [Michael Armbrust] Add a test case / question about uncaching semantics. 63a23e4 [Michael Armbrust] Perform caching on analyzed instead of optimized plan. 03f1cfe [Michael Armbrust] Clean-up / add tests to SameResult suite.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IllegalStateException is thrown. ApplicationMaster registers a shutdown hook and it calls ApplicationMaster#cleanupStagingDir. cleanupStagingDir invokes FileSystem.get(yarnConf) and it invokes FileSystem.getInternal. FileSystem.getInternal also registers shutdown hook. In FileSystem of hadoop 0.23, the shutdown hook registration does not consider whether shutdown is in progress or not (In 2.2, it's considered). // 0.23 if (map.isEmpty() ) { ShutdownHookManager.get().addShutdownHook(clientFinalizer, SHUTDOWN_HOOK_PRIORITY); } // 2.2 if (map.isEmpty() && !ShutdownHookManager.get().isShutdownInProgress()) { ShutdownHookManager.get().addShutdownHook(clientFinalizer, SHUTDOWN_HOOK_PRIORITY); } Thus, in 0.23, another shutdown hook can be registered when ApplicationMaster's shutdown hook run.
