* [DOC][SQL] update out-of-date code snippets using SQLContext in all documents.WeichenXu2016-07-062-20/+23
| | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? I search the whole documents directory using SQLContext, and update the following places: - docs/configuration.md, sparkR code snippets. - docs/streaming-programming-guide.md, several example code. ## How was this patch tested? N/A Author: WeichenXu <WeichenXu123@outlook.com> Closes #14025 from WeichenXu123/WIP_SQLContext_update.
* [MINOR][DOCS] Remove unused images; crush PNGs that could use it for good ↵Sean Owen2016-07-0425-0/+0
| | | | | | | | | | | | | | | | | | measure ## What changes were proposed in this pull request? Coincidentally, I discovered that a couple images were unused in `docs/`, and then searched and found more, and then realized some PNGs were pretty big and could be crushed, and before I knew it, had done the same for the ASF site (not committed yet). No functional change at all, just less superfluous image data. ## How was this patch tested? `jekyll serve` Author: Sean Owen <sowen@cloudera.com> Closes #14029 from srowen/RemoveCompressImages.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | guide example snippets from source files instead of hard code them ## What changes were proposed in this pull request? I extract 6 example programs from GraphX programming guide and replace them with `include_example` label. The 6 example programs are: - AggregateMessagesExample.scala - SSSPExample.scala - TriangleCountingExample.scala - ConnectedComponentsExample.scala - ComprehensiveExample.scala - PageRankExample.scala All the example code can run using `bin/run-example graphx.EXAMPLE_NAME` ## How was this patch tested? Manual. Author: WeichenXu <WeichenXu123@outlook.com> Closes #14015 from WeichenXu123/graphx_example_plugin.
* [GRAPHX][EXAMPLES] move graphx test data directory and update graphx documentWeichenXu2016-07-021-9/+9
| | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? There are two test data files used for graphx examples existing in directory "graphx/data" I move it into "data/" directory because the "graphx" directory is used for code files and other test data files (such as mllib, streaming test data) are all in there. I also update the graphx document where reference the data files which I move place. ## How was this patch tested?

* [SPARK-15990][YARN] Add rolling log aggregation support for Spark on yarnjerryshao2016-06-291-0/+24
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Yarn supports rolling log aggregation since 2.6, previously log will only be aggregated to HDFS after application is finished, it is quite painful for long running applications like Spark Streaming, thriftserver. Also out of disk problem will be occurred when log file is too large. So here propose to add support of rolling log aggregation for Spark on yarn. One limitation for this is that log4j should be set to change to file appender, now in Spark itself uses console appender by default, in which file will not be created again once removed after aggregation. But I think lots of production users should have changed their log4j configuration instead of default on, so this is not a big problem. ## How was this patch tested? Manually verified with Hadoop 2.7.1. Author: jerryshao <sshao@hortonworks.com> Closes #13712 from jerryshao/SPARK-15990.

* [SPARK-13723][YARN] Change behavior of --num-executors with dynamic allocation.Ryan Blue2016-06-232-1/+4
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This changes the behavior of --num-executors and spark.executor.instances when using dynamic allocation. Instead of turning dynamic allocation off, it uses the value for the initial number of executors. This changes was discussed on [SPARK-13723](https://issues.apache.org/jira/browse/SPARK-13723). I highly recommend using it while we can change the behavior for 2.0.0. In practice, the 1.x behavior causes unexpected behavior for users (it is not clear that it disables dynamic allocation) and wastes cluster resources because users rarely notice the log message. ## How was this patch tested? This patch updates tests and adds a test for Utils.getDynamicAllocationInitialExecutors. Author: Ryan Blue <blue@apache.org> Closes #13338 from rdblue/SPARK-13723-num-executors-with-dynamic-allocation.

* [SPARK-15186][ML][DOCS] Add user guide for generalized linear regressionsethah2016-05-271-0/+132
| | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This patch adds a user guide section for generalized linear regression and includes the examples from [#12754](https://github.com/apache/spark/pull/12754). ## How was this patch tested? Documentation only, no tests required. ## Approach In general, it is a bit unclear what level of detail ought to be included in the user guide since there is a lot of variability within the current user guide. I tried to give a fairly brief mathematical introduction to GLMs, and cover what types of problems they could be used for. Additionally, I included a brief blurb on the IRLS solver. The input/output columns are given in a table as is found elsewhere in the docs (though, again, these appear rather intermittently in the current docs), as well as a table providing the supported families and their link functions.
