[jira] [Commented] (ACCUMULO-1085) make the number of threads for assignment configurable

    [ https://issues.apache.org/jira/browse/ACCUMULO-1085?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14204212#comment-14204212 ] 

Josh Elser commented on ACCUMULO-1085:
--------------------------------------

Stumbled across this one. Perhaps we could start running assignments in serial and, when we get far enough to know that there is no recovery to perform, we could kick off another assignment. Would help speed up the normal case, while being able to push the memory issues down the road.
