* [SPARK-18432][DOC] Changed HDFS default block size from 64MB to 128MBNoritaka Sekiyama2016-11-141-2/+2

* [MINOR][DOC] Add an up-to-date description for default serialization during ↵Dongjoon Hyun2016-09-301-0/+1
| | | | | | | | | | | | | | | | shuffling ## What changes were proposed in this pull request? This PR aims to make the doc up-to-date. The documentation is generally correct, but after https://issues.apache.org/jira/browse/SPARK-13926, Spark starts to choose Kyro as a default serialization library during shuffling of simple types, arrays of simple types, or string type. ## How was this patch tested? This is a documentation update. Author: Dongjoon Hyun <dongjoon@apache.org> Closes #15315 from dongjoon-hyun/SPARK-DOC-SERIALIZER.

* [SPARK-15796][CORE] Reduce spark.memory.fraction default to avoid ↵Sean Owen2016-06-161-1/+17
| | | | | | | | | | | | | | | | overrunning old gen in JVM default config ## What changes were proposed in this pull request? Reduce `spark.memory.fraction` default to 0.6 in order to make it fit within default JVM old generation size (2/3 heap). See JIRA discussion. This means a full cache doesn't spill into the new gen. CC andrewor14 ## How was this patch tested? Jenkins tests. Author: Sean Owen <sowen@cloudera.com> Closes #13618 from srowen/SPARK-15796.
* [SPARK-12081] Make unified memory manager work with small heapsAndrew Or2015-12-011-1/+1
| | | | | | | | | | The existing `spark.memory.fraction` (default 0.75) gives the system 25% of the space to work with. For small heaps, this is not enough: e.g. default 1GB leaves only 250MB system memory. This is especially a problem in local mode, where the driver and executor are crammed in the same JVM. Members of the community have reported driver OOM's in such cases. **New proposal.** We now reserve 300MB before taking the 75%. For 1GB JVMs, this leaves `(1024 - 300) * 0.75 = 543MB` for execution and storage. This is proposal (1) listed in the [JIRA](https://issues.apache.org/jira/browse/SPARK-12081).

| | | | | | | | | | | | | | | | | | "The best way to size the amount of memory consumption your dataset will require is to create an RDD, put it into cache, and look at the SparkContext logs on your driver program. The logs will tell you how much memory each partition is consuming, which you can aggregate to get the total size of the RDD." -the Tuning Spark page This is a pain.

* SPARK-3526 Add section about data locality to the tuning guideAndrew Ash2014-12-101-0/+33
| | | | | | | | | | | | | | | | | 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. Is the idea to wait longer and hope for the rack-local tasks to turn into node-local or better? - Will there be a datacenter-local locality level in the future?

* [SPARK-1439, SPARK-1440] Generate unified Scaladoc across projects and JavadocsMatei Zaharia2014-04-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | I used the sbt-unidoc plugin (https://github.com/sbt/sbt-unidoc) to create a unified Scaladoc of our public packages, and generate Javadocs as well. One limitation is that I haven't found an easy way to exclude packages in the Javadoc; there is a SBT task that identifies Java sources to run javadoc on, but it's been very difficult to modify it from outside to change what is set in the unidoc package. Some SBT-savvy people should help with this. The Javadoc site also lacks package-level descriptions and things like that, so we may want to look into that. We may decide not to post these right now if it's too limited compared to the Scala one.

* SPARK-929: Fully deprecate usage of SPARK_MEMAaron Davidson2014-03-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | (Continued from old repo, prior discussion at https://github.com/apache/incubator-spark/pull/615) This patch cements our deprecation of the SPARK_MEM environment variable by replacing it with three more specialized variables: SPARK_DAEMON_MEMORY, SPARK_EXECUTOR_MEMORY, and SPARK_DRIVER_MEMORY The creation of the latter two variables means that we can safely set driver/job memory without accidentally setting the executor memory. Neither is public. SPARK_EXECUTOR_MEMORY is only used by the Mesos scheduler (and set within SparkContext). The proper way of configuring executor memory is through the "spark.executor.memory" property. SPARK_DRIVER_MEMORY is the new way of specifying the amount of memory run by jobs launched by spark-class, without possibly affecting executor memory. Other memory considerations: - The repl's memory can be set through the "--drivermem" command-line option, which really just sets SPARK_DRIVER_MEMORY. - run-example doesn't use spark-class, so the only way to modify examples' memory is actually an unusual use of SPARK_JAVA_OPTS (which is normally overriden in all cases by spark-class). This patch also fixes a lurking bug where spark-shell misused spark-class (the first argument is supposed to be the main class name, not java options), as well as a bug in the Windows spark-class2.cmd. I have not yet tested this patch on either Windows or Mesos, however.
