Sean Owen commented on SPARK-9487: ---------------------------------- Look at its superclass (trait) that defines "sc", which sets local[2]. This may be hard to update all tests to make them work with a slightly different number of threads. It's great if we can get this done, but if you're having difficulty troubleshooting the various failures that may occur, I think it may be best to abandon this. It's hard to assist with every failure here. > Use the same num. worker threads in Scala/Python unit tests > ----------------------------------------------------------- > > Key: SPARK-9487 > URL: https://issues.apache.org/jira/browse/SPARK-9487 > Project: Spark > Issue Type: Improvement > Components: PySpark, Spark Core, SQL, Tests > Affects Versions: 1.5.0 > Reporter: Xiangrui Meng > Labels: starter > Attachments: ContextCleanerSuiteResults, HeartbeatReceiverSuiteResults > > > In Python we use `local[4]` for unit tests, while in Scala/Java we use > `local[2]` and `local` for some unit tests in SQL, MLLib, and other > components. If the operation depends on partition IDs, e.g., random number > generator, this will lead to different result in Python and Scala/Java. It > would be nice to use the same number in all unit tests. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
