Amareshwari Sriramadasu commented on MAPREDUCE-927:
---------------------------------------------------
bq. The logscleanup thread is not joined/killed in the TaskTracker.close(). So,
there will 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 constructor.
> Cleanup of task-logs should happen in TaskTracker instead of the Child

> Task logs' cleanup is being done in Child now. This is undesirable atleast
> for two reasons: 1) failures while cleaning up will affect the user's tasks,
> and 2) the task's wall time will get affected due to operations that TT
> actually should own.
