Hi, using pyspark 1.1.0 on YARN 2.5.0. all operations run nicely in parallel - I can seen multiple python processes spawned on each nodemanager but from some reason when running cartesian there is only single python process running on each node. the task is indicating thousands of partitions so don't understand why it is not running with higher parallelism. the performance is obviously poor although other operation rocks.
any idea how to improve this? thank you, Antony. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
