[jira] [Created] (BEAM-15) Applying windowing to cached RDDs fails

Amit Sela created BEAM-15:
-----------------------------

             Summary: Applying windowing to cached RDDs fails
                 Key: BEAM-15
                 URL: https://issues.apache.org/jira/browse/BEAM-15
             Project: Beam
          Issue Type: Bug
          Components: runner-spark
            Reporter: Amit Sela
            Assignee: Amit Sela


The Spark runner caches RDDs that are accessed more than once. If applying window operations to a cached RDD, it will fail because windowed RDDs will try to cache with a different cache level - windowing cache level is StorageLevel.MEMORY_ONLY_SER and RDD cache level is StorageLevel.MEMORY_ONLY.
