* [SPARK-14342][CORE][DOCS][TESTS] Remove straggler references to TachyonLiwei Lin2016-04-022-3/+3
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Straggler references to Tachyon were removed: - for docs, `tachyon` has been generalized as `off-heap memory`; - for Mesos test suits, the key-value `tachyon:true`/`tachyon:false` has been changed to `os:centos`/`os:ubuntu`, since `os` is an example constrain used by the [Mesos official docs](http://mesos.apache.org/documentation/attributes-resources/). ## How was this patch tested? Existing test suites. Author: Liwei Lin <lwlin7@gmail.com> Closes #12129 from lw-lin/tachyon-cleanup.
* [SPARK-12343][YARN] Simplify Yarn client and client argumentjerryshao2016-04-011-0/+7
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Currently in Spark on YARN, configurations can be passed through SparkConf, env and command arguments, some parts are duplicated, like client argument and SparkConf. So here propose to simplify the command arguments. ## How was this patch tested? This patch is tested manually with unit test. CC vanzin tgravescs , please help to suggest this proposal. The original purpose of this JIRA is to remove `ClientArguments`, through refactoring some arguments like `--class`, `--arg` are not so easy to replace, so here I remove the most part of command line arguments, only keep the minimal set. Author: jerryshao <sshao@hortonworks.com> Closes #11603 from jerryshao/SPARK-12343.
* [SPARK-14281][TESTS] Fix java8-tests and simplify their buildJosh Rosen2016-03-311-4/+4

* [Docs] Update monitoring.md to accurately describe the history serverMichael Gummelt2016-03-311-29/+29
| | | | | | | | | | | | | | It looks like the docs were recently updated to reflect the History Server's support for incomplete applications, but they still had wording that suggested only completed applications were viewable. This fixes that. My editor also introduced several whitespace removal changes, that I hope are OK, as text files shouldn't have trailing whitespace. To verify they're purely whitespace changes, add `&w=1` to your browser address. If this isn't acceptable, let me know and I'll update the PR. I also didn't think this required a JIRA. Let me know if I should create one. Not tested Author: Michael Gummelt <mgummelt@mesosphere.io> Closes #12045 from mgummelt/update-history-docs.

| | | | | | | | | | | | | | | | | | | | | using include_example Replace example code in mllib-feature-extraction.md using include_example https://issues.apache.org/jira/browse/SPARK-13017 The example code in the user guide is embedded in the markdown and hence it is not easy to test. It would be nice to automatically test them. This JIRA is to discuss options to automate example code testing and see what we can do in Spark 1.6. Goal is to move actual example code to spark/examples and test compilation in Jenkins builds. Then in the markdown, we can reference part of the code to show in the user guide. This requires adding a Jekyll tag that is similar to https://github.com/jekyll/jekyll/blob/master/lib/jekyll/tags/include.rb, e.g., called include_example. `{% include_example scala/org/apache/spark/examples/mllib/TFIDFExample.scala %}` Jekyll will find `examples/src/main/scala/org/apache/spark/examples/mllib/TFIDFExample.scala` and pick code blocks marked "example" and replace code block in `{% highlight %}` in the markdown.

| | | | | | | | | | | | | | | | | | | | | | mllib-statistics.md using include_example ## What changes were proposed in this pull request? This PR for ticket SPARK-13019 is based on previous PR(https://github.com/apache/spark/pull/11108). Since PR(https://github.com/apache/spark/pull/11108) is breaking scala-2.10 build, more work is needed to fix build errors. What I did new in this PR is adding keyword argument for 'fractions': ` val approxSample = data.sampleByKey(withReplacement = false, fractions = fractions)` ` val exactSample = data.sampleByKeyExact(withReplacement = false, fractions = fractions)` I reopened ticket on JIRA but sorry I don't know how to reopen a GitHub pull request, so I just submitting a new pull request. ## How was this patch tested? Manual build testing on local machine, build based on scala-2.10. Author: Xin Ren <iamshrek@126.com> Closes #11901 from keypointt/SPARK-13019.

When studying spark many users just copy examples on the documentation and paste on their terminals and because of that the missing backlashes lead them run into some shell errors. The added backslashes avoid that problem for spark users with that behavior. ## How was this patch tested? I generated the documentation locally using jekyll and checked the generated pages Author: Daniel Santana <mestresan@gmail.com> Closes #11699 from danielsan/master.

| | | | | | | | | | | | | | | | | | | | byte[] conversions (and remaining Coverity items) ## What changes were proposed in this pull request? - Fixes calls to `new String(byte[])` or `String.getBytes()` that rely on platform default encoding, to use UTF-8 - Same for `InputStreamReader` and `OutputStreamWriter` constructors - Standardizes on UTF-8 everywhere - Standardizes specifying the encoding with `StandardCharsets.UTF-8`, not the Guava constant or "UTF-8" (which means handling `UnuspportedEncodingException`) - (also addresses the other remaining Coverity scan issues, which are pretty trivial; these are separated into commit https://github.com/srowen/spark/commit/1deecd8d9ca986d8adb1a42d315890ce5349d29c ) ## How was this patch tested?

* [SPARK-13577][YARN] Allow Spark jar to be multiple jars, archive.Marcelo Vanzin2016-03-111-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | In preparation for the demise of assemblies, this change allows the YARN backend to use multiple jars and globs as the "Spark jar". The config option has been renamed to "spark.yarn.jars" to reflect that. A second option "spark.yarn.archive" was also added; if set, this takes precedence and uploads an archive expected to contain the jar files with the Spark code and its dependencies. Existing deployments should keep working, mostly. This change drops support for the "SPARK_JAR" environment variable, and also does not fall back to using "jarOfClass" if no configuration is set, falling back to finding files under SPARK_HOME instead. This should be fine since "jarOfClass" probably wouldn't work unless you were using spark-submit anyway. Tested with the unit tests, and trying the different config options on a YARN cluster. Author: Marcelo Vanzin <vanzin@cloudera.com> Closes #11500 from vanzin/SPARK-13577.

* [SPARK-13492][MESOS] Configurable Mesos framework webui URL.Sergiusz Urbaniak2016-03-091-0/+16
| | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Previously the Mesos framework webui URL was being derived only from the Spark UI address leaving no possibility to configure it. This commit makes it configurable. If unset it falls back to the previous behavior. Motivation: This change is necessary in order to be able to install Spark on DCOS and to be able to give it a custom service link. The configured `webui_url` is configured to point to a reverse proxy in the DCOS environment. ## How was this patch tested? Locally, using unit tests and on DCOS testing and stable revision. Author: Sergiusz Urbaniak <sur@mesosphere.io> Closes #11369 from s-urbaniak/sur-webui-url.

| | | | | | | | | | | | | | | | | | | | | | | | | creation in Java code. ## What changes were proposed in this pull request? In order to make `docs/examples` (and other related code) more simple/readable/user-friendly, this PR replaces existing codes like the followings by using `diamond` operator. ``` - final ArrayList<Product2<Object, Object>> dataToWrite = - new ArrayList<Product2<Object, Object>>(); + final ArrayList<Product2<Object, Object>> dataToWrite = new ArrayList<>(); ``` Java 7 or higher supports **diamond** operator which replaces the type arguments required to invoke the constructor of a generic class with an empty set of type parameters (<>). Currently, Spark Java code use mixed usage of this. ## How was this patch tested? Manual. Pass the existing tests. Author: Dongjoon Hyun <dongjoon@apache.org> Closes #11541 from dongjoon-hyun/SPARK-13702.

* [SPARK-13596][BUILD] Move misc top-level build files into appropriate subdirsSean Owen2016-03-072-5/+5
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Move many top-level files in dev/ or other appropriate directory. In particular, put `make-distribution.sh` in `dev` and update docs accordingly. Remove deprecated `sbt/sbt`. I was (so far) unable to figure out how to move `tox.ini`. `scalastyle-config.xml` should be movable but edits to the project `.sbt` files didn't work; config file location is updatable for compile but not test scope. ## How was this patch tested? `./dev/run-tests` to verify RAT and checkstyle work. Jenkins tests for the rest. Author: Sean Owen <sowen@cloudera.com> Closes #11522 from srowen/SPARK-13596.

| | | | | | | | | | | | | | ## What changes were proposed in this pull request? We provide a very limited set of cluster management script in Spark for Tachyon, although Tachyon itself provides a much better version of it. Given now Spark users can simply use Tachyon as a normal file system and does not require extensive configurations, we can remove this management capabilities to simplify Spark bash scripts. Note that this also reduces coupling between a 3rd party external system and Spark's release scripts, and would eliminate possibility for failures such as Tachyon being renamed or the tar balls being relocated. ## How was this patch tested?

In the firest batch task ,receivers receive data at the maximum speed they can reach,it might exhaust executors memory resources. Add a initial input rate limit value can make sure the Streaming job execute success in the first batch,then the backpressure mechanism can adjust receiving rate adaptively.

* [SPARK-13018][DOCS] Replace example code in mllib-pmml-model-export.md using ↵Xin Ren2016-02-151-32/+3
| | | | | | | | | | | | | | | | | | | | | include_example Replace example code in mllib-pmml-model-export.md using include_example https://issues.apache.org/jira/browse/SPARK-13018 The example code in the user guide is embedded in the markdown and hence it is not easy to test. It would be nice to automatically test them. This JIRA is to discuss options to automate example code testing and see what we can do in Spark 1.6. Goal is to move actual example code to spark/examples and test compilation in Jenkins builds. Then in the markdown, we can reference part of the code to show in the user guide. This requires adding a Jekyll tag that is similar to https://github.com/jekyll/jekyll/blob/master/lib/jekyll/tags/include.rb, e.g., called include_example. `{% include_example scala/org/apache/spark/examples/mllib/PMMLModelExportExample.scala %}` Jekyll will find `examples/src/main/scala/org/apache/spark/examples/mllib/PMMLModelExportExample.scala` and pick code blocks marked "example" and replace code block in `{% highlight %}` in the markdown.
