Hong Shen updated SPARK-5421:
-----------------------------
Description:
ExternalAppendOnlyMap if only for the spark job that aggregator isDefined, but
sparkSQL's shuffledRDD haven't define aggregator, so sparkSQL won't spill at
shuffle, it's very easy to throw OOM at shuffle.
One of the executor's log, here is stderr:
15/01/27 07:02:19 INFO spark.MapOutputTrackerWorker: Don't have map outputs for
shuffle 1, fetching them
15/01/27 07:02:19 INFO spark.MapOutputTrackerWorker: Doing the fetch; tracker
