Zombie tasks remain after jobs finish/fail/get killed
-----------------------------------------------------
Key: HADOOP-5330
URL: https://issues.apache.org/jira/browse/HADOOP-5330
Project: Hadoop Core
Issue Type: Bug
Affects Versions: 0.19.1
Reporter: Nathan Marz
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.
