> ----------------------------------------------------------
>
> Key: HADOOP-4161
> URL: https://issues.apache.org/jira/browse/HADOOP-4161
> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/hod
> Reporter: Vinod K V
> Assignee: Vinod K V
> Fix For: 0.18.1, 0.19.0
>
>
> In hod-client, we have
> {code}
> sys.exit(hod.operation())
> sys.exit(hod.script())
> {code}
> sys.exit(opCode) makes sure that the client is truly cleaned up, killing unjoined threads etc. So, exceptions not caught by hodRunner.operation() or hodRunner.script(), will by-pass sys.exit method and thus can potentially hang hod-client.
> For e.g., when hod allocate fails after allocation and before service-registry thread is cleaned up, hod client will hang.
