Subject [jira] Commented: (MAPREDUCE-927) Cleanup of task-logs should happen in TaskTracker instead of the Child

be zombie threads in the system on a re-init and may well interfere with the new thread.
I just realized that the thread is initialized in intialize() method. It should be moved to

> Task logs' cleanup is being done in Child now. This is undesirable atleast for two reasons:
