* [SPARK-5254][MLLIB] Update the user guide to position spark.ml betterXiangrui Meng2015-01-142-14/+21
| | | | | | | | | | | | | | | | The current statement in the user guide may deliver confusing messages to users. spark.ml contains high-level APIs for building ML pipelines. But it doesn't mean that spark.mllib is being deprecated. First of all, the pipeline API is in its alpha stage and we need to see more use cases from the community to stabilizes it, which may take several releases. Secondly, the components in spark.ml are simple wrappers over spark.mllib implementations. Neither the APIs or the implementations from spark.mllib are being deprecated. We expect users use spark.ml pipeline APIs to build their ML pipelines, but we will keep supporting and adding features to spark.mllib. For example, there are many features in review at https://spark-prs.appspot.com/#mllib. So users should be comfortable with using spark.mllib features and expect more coming. The user guide needs to be updated to make the message clear.

* SPARK-5136 [DOCS] Improve documentation around setting up Spark IntelliJ projectSean Owen2015-01-091-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR simply points to the IntelliJ wiki page instead of also including IntelliJ notes in the docs. The intent however is to also update the wiki page with updated tips. This is the text I propose for the IntelliJ section on the wiki. I realize it omits some of the existing instructions on the wiki, about enabling Hive, but I think those are actually optional. ------ IntelliJ supports both Maven- and SBT-based projects. It is recommended, however, to import Spark as a Maven project. Choose "Import Project..." from the File menu, and select the `pom.xml` file in the Spark root directory. It is fine to leave all settings at their default values in the Maven import wizard, with two caveats. First, it is usually useful to enable "Import Maven projects automatically", sincchanges to the project structure will automatically update the IntelliJ project. Second, note the step that prompts you to choose active Maven build profiles. As documented above, some build configuration require specific profiles to be enabled. The same profiles that are enabled with `-P[profile name]` above may be enabled on this screen. For example, if developing for Hadoop 2.4 with YARN support, enable profiles `yarn` and `hadoop-2.4`. These selections can be changed later by accessing the "Maven Projects" tool window from the View menu, and expanding the Profiles section. "Rebuild Project" can fail the first time the project is compiled, because generate source files are not automatically generated. Try clicking the "Generate Sources and Update Folders For All Projects" button in the "Maven Projects" tool window to manually generate these sources. Compilation may fail with an error like "scalac: bad option: -P:/home/jakub/.m2/repository/org/scalamacros/paradise_2.10.4/2.0.1/paradise_2.10.4-2.0.1.jar". If so, go to Preferences > Build, Execution, Deployment > Scala Compiler and clear the "Additional compiler options" field. It will work then although the option will come back when the project reimports.

* [SPARK-4835] Disable validateOutputSpecs for Spark Streaming jobsJosh Rosen2015-01-041-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | This patch disables output spec. validation for jobs launched through Spark Streaming, since this interferes with checkpoint recovery. Hadoop OutputFormats have a `checkOutputSpecs` method which performs certain checks prior to writing output, such as checking whether the output directory already exists. SPARK-1100 added checks for FileOutputFormat, SPARK-1677 (#947) added a SparkConf configuration to disable these checks, and SPARK-2309 (#1088) extended these checks to run for all OutputFormats, not just FileOutputFormat. In Spark Streaming, we might have to re-process a batch during checkpoint recovery, so `save` actions may be called multiple times. In addition to `DStream`'s own save actions, users might use `transform` or `foreachRDD` and call the `RDD` and `PairRDD` save actions. When output spec. validation is enabled, the second calls to these actions will fail due to existing output. This patch automatically disables output spec. validation for jobs submitted by the Spark Streaming scheduler. This is done by using Scala's `DynamicVariable` to propagate the bypass setting without having to mutate SparkConf or introduce a global variable.

| | | | | | | | | | | | | | | | | | | | cc kayousterhout I have a few outstanding questions from compiling this documentation: - What's the difference between NO_PREF and ANY? I understand the implications of the ordering but don't know what an example of each would be - Why is NO_PREF ahead of RACK_LOCAL? I would think it'd be better to schedule rack-local tasks ahead of no preference if you could only do one or the other.

(small bug fix) Note: I know this is a lot of lines, but most is covered by: * Programming guide sections for gradient boosting and random forests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://issues.apache.org/jira/browse/SPARK-3628 In current implementation, the accumulator will be updated for every successfully finished task, even the task is from a resubmitted stage, which makes the accumulator counter-intuitive In this patch, I changed the way for the DAGScheduler to update the accumulator, DAGScheduler maintains a HashTable, mapping the stage id to the received <accumulator_id , value> pairs. Only when the stage becomes independent, (no job needs it any more), we accumulate the values of the <accumulator_id , value> pairs, when a task finished, we check if the HashTable has contained such stageId, it saves the accumulator_id, value only when the task is the first finished task of a new stage or the stage is running for the first attempt...
