| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | maven/zinc/scalac Creates a top level directory script (as `build/mvn`) to automatically download zinc and the specific version of scala used to easily build spark. This will also download and install maven if the user doesn't already have it and all packages are hosted under the `build/` directory. Tested on both Linux and OSX OS's and both work. All commands pass through to the maven binary so it acts exactly as a traditional maven call would.

* [SPARK-4913] Fix incorrect event log pathLiang-Chi Hsieh2014-12-232-5/+17
| | | | | | | | | | | | | | | SPARK-2261 uses a single file to log events for an app. `eventLogDir` in `ApplicationDescription` is replaced with `eventLogFile`. However, `ApplicationDescription` in `SparkDeploySchedulerBackend` is initialized with `SparkContext`'s `eventLogDir`. It is just the log directory, not the actual log file path. `Master.rebuildSparkUI` can not correctly rebuild a new SparkUI for the app. Because the `ApplicationDescription` is remotely registered with `Master` and the app's id is then generated in `Master`, we can not get the app id in advance before registration. So the received description needs to be modified with correct `eventLogFile` value.

| | | | | | | | | | | | | | | | | | | This PR tries to fix the Hive tests failure encountered in PR #3157 by cleaning `lib_managed` before building assembly jar against Hive 0.13.1 in `dev/run-tests`. Otherwise two sets of datanucleus jars would be left in `lib_managed` and may mess up class paths while executing Hive test suites. Please refer to [this thread] [1] for details. A clean build would be even safer, but we only clean `lib_managed` here to save build time. This PR also takes the chance to clean up some minor typos and formatting issues in the comments.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 7aacb7bfa added support for sharing downloaded files among multiple executors of the same app. That works great in Yarn, since the app's directory is cleaned up after the app is done. But Spark standalone mode didn't do that, so the lock/cache files created by that change were left around and could eventually fill up the disk hosting /tmp. To solve that, create app-specific directories under the local dirs when launching executors. Multiple executors launched by the same Worker will use the same app directories, so they should be able to share the downloaded files. When the application finishes, a new message is sent to all workers telling them the application has finished; once that message has been received, and all executors registered for the application shut down, then those directories will be cleaned up by the Worker. Note: Unit testing this is hard (if even possible), since local-cluster mode doesn't seem to leave the Master/Worker daemons running long enough after `sc.stop()` is called for the clean up protocol to take effect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Scala, `map` and `flatMap` of `Iterable` will copy the contents of `Iterable` to a new `Seq`.

* [SPARK-4079] [CORE] Consolidates Errors if a CompressionCodec is not availableKostas Sakellis2014-12-222-6/+27
| | | | | | | | | | | | | | This commit consolidates some of the exceptions thrown if compression codecs are not available. If a bad configuration string was passed in, a ClassNotFoundException was through. Also, if Snappy was not available, it would throw an InvocationTargetException when the codec was being used (not when it was being initialized). Now, an IllegalArgumentException is thrown when a codec is not available at creation time - either because the class does not exist or the codec itself is not available in the system. This will allow us to have a better message and fail faster.

* [SPARK-2075][Core] Make the compiler generate same bytes code for Hadoop 1.+ ↵zsxwing2014-12-216-6/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and Hadoop 2.+ `NullWritable` is a `Comparable` rather than `Comparable[NullWritable]` in Hadoop 1.+, so the compiler cannot find an implicit Ordering for it. It will generate different anonymous classes for `saveAsTextFile` in Hadoop 1.+ and Hadoop 2.+. Therefore, here we provide an Ordering for NullWritable so that the compiler will generate same codes. I used the following commands to confirm the generated byte codes are some. ``` mvn -Dhadoop.version=1.2.1 -DskipTests clean package -pl core -am javap -private -c -classpath core/target/scala-2.10/classes org.apache.spark.rdd.RDD > ~/hadoop1.txt mvn -Pyarn -Phadoop-2.2 -Dhadoop.version=2.2.0 -DskipTests clean package -pl core -am javap -private -c -classpath core/target/scala-2.10/classes org.apache.spark.rdd.RDD > ~/hadoop2.txt diff ~/hadoop1.txt ~/hadoop2.txt ``` However, the compiler will generate different codes for the classes which call methods of `JobContext/TaskAttemptContext`. `JobContext/TaskAttemptContext` is a class in Hadoop 1.+, and calling its method will use `invokevirtual`, while it's an interface in Hadoop 2.+, and will use `invokeinterface`. To fix it, we can use reflection to call `JobContext/TaskAttemptContext.getConfiguration`.
