David Ginzburg commented on MAPREDUCE-2638:
-------------------------------------------
I'm not sure this is related to this issue, but I suspect preemption causes
Inconsistent result when fairscheduler preemption is on.
I have reported it at
http://mail-archives.apache.org/mod_mbox/hadoop-mapreduce-user/201201.mbox/%[email protected]%3E
Maybe this stress test can help reproduce it easily, on clusters other than the
one I'm running.
