[jira] Commented: (HADOOP-5247) NPEs in JobTracker and JobClient
when mapred.jobtracker.completeuserjobs.maximum is set to zero.
[ https://issues.apache.org/jira/browse/HADOOP-5247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12849036#action_12849036 ]
Charles Butterfield commented on HADOOP-5247:
---------------------------------------------
I'm running 0.20.2 and have just gotten an NPE calling NetworkedJob.isComplete(), while the DFS is under heavy stress (multiple node removed from service).
This seems to be exactly the case that Vinod identified last year. I could not find any open ticket. Should this ticket be reopened? Please advice.
