[jira] [Commented] (SPARK-2125) Add sorting flag to ShuffleManager, and implement it in HashShuffleManager

    [ https://issues.apache.org/jira/browse/SPARK-2125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14028833#comment-14028833 ] 

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.
