Saisai Shao commented on SPARK-2125:
------------------------------------
Hi Matei, for moving sort into hash shuffle implementation, are you planning to
use ExternalAppendOnlyMap as [PR931|https://github.com/apache/spark/pull/931]
described, or leave it as current implementation in OrderedRDDFuntions to put
the whole partition into memory to sort.
> Add sorting flag to ShuffleManager, and implement it in HashShuffleManager
