Subject [jira] [Commented] (MAPREDUCE-4398) Fix mapred.system.dir permission error with FairScheduler
Date Sun, 14 Oct 2012 08:50:03 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4398?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13475804#comment-13475804
] 

Luke Lu commented on MAPREDUCE-4398:
------------------------------------

A workaround is to submit 4 or more jobs as the user of the jobtracker and everything will
work fine afterwards. BTW, IBM BigInsights community version (open source) contains the right
fix (properly initialize job init threads) to fairscheduler since BigInsights 1.3.0.1. Unfortunately
IBM devs are too busy to port/submit the patches to Apache right now :)
