[jira] [Commented] (MAPREDUCE-3973) [Umbrella JIRA] JobHistoryServer performance improvements in YARN+MR

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3973?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14582179#comment-14582179 ] 

Ray Chiang commented on MAPREDUCE-3973:
---------------------------------------

Just a quick FYI, I've added the three scaling issues for JobHistoryServer to this umbrella JIRA rather than open a second "JHS Performance Umbrella JIRA".
