Lou DeGenaro updated UIMA-2591:
-------------------------------
Component/s: DUCC
> Provide ability to cancel an individual DUCC Job Process
> ---------------------------------------------------------
>
> Key: UIMA-2591
> URL: https://issues.apache.org/jira/browse/UIMA-2591
> Project: UIMA
> Issue Type: New Feature
> Components: DUCC
> Reporter: Lou DeGenaro
> Assignee: Lou DeGenaro
> Priority: Minor
>
> Presently, a DUCC Job may be unable to make forward progress (including
> termination) due to a Job Process [JP] that was dispatched to an Agent that
> is no longer communicating. The only way to rescue this Job (without
> recylcing DUCC itself) is to have the Agent start reporting again, which may
> not be feasible (for example a HW problem has caused the system to crash and
> precludes system boot and therefore Agent from running).
> Provided here is the ability to cancel a particular JP, thus making any and
> all incomplete Work Items previously dispatched to that JP re-deployable
> elsewhere.
> The DUCC CLI is enhanced to provide the --dpid flag to the job cancel command.
> Note well: if there is any possibility that the target JP is active but the
> Agent is not, then this flag should not be used, so as to avoid the
> possibility of the same Work Item being processed by two JPs simultaneously.
