Subject [jira] Commented: (HADOOP-5330) Zombie tasks remain after jobs finish/fail/get killed

Amareshwari Sriramadasu commented on HADOOP-5330:
-------------------------------------------------

Nathan, now that HADOOP-5247, HADOOP-5269 and HADOOP-5233 are committed to 0.19.2, do you
still see the problem?
If not, can you close the issue?

> I'm seeing a lot of "task attempts" around our hadoop cluster for jobs that are no longer
around. The attempts seem to be "hung", as they sit there forever. Additionally, they seem
to take up map and reduce slots in the cluster unless MapReduce is restarted. This causes
real jobs to be unable to utilize the whole cluster.
