[jira] Commented: (MAPREDUCE-1382) MRAsyncDiscService should tolerate missing local.dir

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12907439#action_12907439 ] 

Scott Chen commented on MAPREDUCE-1382:
---------------------------------------

> Currently when some of the local.dir do not exist, MRAsyncDiscService will fail. It should only fail when all directories don't work.
