* [MINOR] Remove unused arg in als.pyZheng RuiFeng2016-07-181-3/+3
| | | | | | | | | | | | ## What changes were proposed in this pull request? The second arg in method `update()` is never used. So I delete it. ## How was this patch tested? local run with `./bin/spark-submit examples/src/main/python/als.py` Author: Zheng RuiFeng <ruifengz@foxmail.com> Closes #14247 from zhengruifeng/als_refine.
* [MINOR] [PYSPARK] [EXAMPLES] Changed examples to use ↵Bryan Cutler2016-05-251-1/+1
| | | | | | | | | | | | | | | SparkSession.sparkContext instead of _sc ## What changes were proposed in this pull request? Some PySpark examples need a SparkContext and get it by accessing _sc directly from the session. These examples should use the provided property `sparkContext` in `SparkSession` instead. ## How was this patch tested? Ran modified examples Author: Bryan Cutler <cutlerb@gmail.com> Closes #13303 from BryanCutler/pyspark-session-sparkContext-MINOR.
* [SPARK-15031][EXAMPLE] Use SparkSession in examplesZheng RuiFeng2016-05-201-3/+9
| | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Use `SparkSession` according to [SPARK-15031](https://issues.apache.org/jira/browse/SPARK-15031) `MLLLIB` is not recommended to use now, so examples in `MLLIB` are ignored in this PR. `StreamingContext` can not be directly obtained from `SparkSession`, so example in `Streaming` are ignored too. cc andrewor14 ## How was this patch tested? manual tests with spark-submit Author: Zheng RuiFeng <ruifengz@foxmail.com> Closes #13164 from zhengruifeng/use_sparksession_ii.
* [SPARK-15398][ML] Update the warning message to recommend ML usageZheng RuiFeng2016-05-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? MLlib are not recommended to use, and some methods are even deprecated. Update the warning message to recommend ML usage. ``` def showWarning() { System.err.println( """WARN: This is a naive implementation of Logistic Regression and is given as an example! |Please use either org.apache.spark.mllib.classification.LogisticRegressionWithSGD or |org.apache.spark.mllib.classification.LogisticRegressionWithLBFGS |for more conventional use.

| | | | | | | | | | | | | | | | | | | | | A recent PR (#552) fixed this for all Scala / Java examples. We need to do it for python too. Note that this blocks on #799, which makes `bin/pyspark` go through Spark submit. With only the changes in this PR, the only way to run these examples is through Spark submit. Once #799 goes in, you can use `bin/pyspark` to run them too.
