Resolution: Fixed
> DUCC check_ducc and start_ducc should detect and handle ssh hangs

> Key: UIMA-3814
> URL: https://issues.apache.org/jira/browse/UIMA-3814
> Project: UIMA
> Issue Type: Improvement
> Components: DUCC
> Affects Versions: 1.1.0-Ducc
> Reporter: Jim Challenger
> Assignee: Jim Challenger
> Fix For: 1.1.0-Ducc
>
>
> Broken nodes can cause ssh hangs, e.g. if NFS is broken. Check_ducc and
> start_ducc should handle this.
> Proposed design: it's nearly impossible to stop the ssh without a ctl-c -like
> interrupt if the remote work is stuck in NFS. check_ducc and start_ducc will
> catch the ctl-c, terminate any stuck ssh's, and report on the nodes that
> didn't return correctly.
