> Key: UIMA-3703
> URL: https://issues.apache.org/jira/browse/UIMA-3703
> Project: UIMA
> Issue Type: Improvement
> Components: DUCC
> Affects Versions: 1.0.0-Ducc
> Reporter: Jim Challenger
> Assignee: Jim Challenger
> Priority: Minor
> Fix For: future-DUCC
>
>
> The NodeIdentity should generate a UUID and make it available to interested
> parties. The UUID is to be used by RM and WS and maybe others to detect
> duplicate Agent instances on the same node, the presence of which can cause
> all sorts of problems including permanently "hung" jobs.
> The proposed use of this is for RM to 'blacklist' the duplicate Agents,
> purging all work from them, and refuse to allocate new work on them until
> they are cleaned up and whitelisted again. WS would reveal the problem so
> admins could be aware and clean up.
> Logic to use this will be implemented later under separate JIRAs.
