> [HOD] Idle cluster cleanup does not work if the JobTracker becomes

> Key: HADOOP-2847

> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/hod
> Affects Versions: 0.16.0

>
> In some erroneous conditions, the Hadoop JobTracker becomes unresponsive to
> RPC calls (for e.g. if a misconfiguration causes the JobTracker to run out of
> memory). In such cases, a cluster allocated by HOD no longer runs any jobs
> and is wastefully holding up nodes. The usual idle cluster cleaner should
> deallocate the cluster ideally, but it does not.
