Warren Wang commented on SPARK-4049:
------------------------------------
This issue is really annoying when the rdd is reused for many times. For a
particular execution, the fraction cached will increase 1%-10% unreasonably and
never return back to 100%. When the rdd is reused for hundred times, the
fraction cached will eventually reach to 200%, on which situation the spark job
will crash for no more memory to use. Hope this to be fixed.
