[jira] [Created] (SPARK-7337) FPGrowth algo throwing OutOfMemoryError

Amit Gupta created SPARK-7337:
---------------------------------

             Summary: FPGrowth algo throwing OutOfMemoryError
                 Key: SPARK-7337
                 URL: https://issues.apache.org/jira/browse/SPARK-7337
             Project: Spark
          Issue Type: Bug
          Components: MLlib
    Affects Versions: 1.3.1
         Environment: Ubuntu
            Reporter: Amit Gupta


When running FPGrowth algo with huge data in GBs and with numPartitions=500 then after some time it throws OutOfMemoryError.
Algo runs correctly upto "collect at FPGrowth.scala:131" where it creates 500 tasks. It fails at next stage "flatMap at FPGrowth.scala:150" where it fails to create 500 tasks and create some internal calculated 17 tasks.

I want to attach print screen but couldn't locate option to do that.
