Zombie tasks kept alive by logging system
-----------------------------------------
Key: MAPREDUCE-1755
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1755
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.20.2
Reporter: Allen Wittenauer
I'm currently looking at a task that, as far as the task tracker is concerned,
is dead. Like long long long ago dead. It was a failed task that ran out of
heap. Rather than just kill it, I thought I would see what it was doing, since
it was clearly using system resources. It would appear the system is trying to
log but failing. I'm guessing we're missing an error condition and not doing
the appropriate thing. See the comments for more.
