Lou DeGenaro updated UIMA-2641:
-------------------------------
Component/s: DUCC
> DUCC orchestrator (OR) should mark unused, stubbornly alive Job Processes
> (JPs) as "Stopped" when all work items are accounted for...

> Project: UIMA
> Issue Type: Improvement
> Components: DUCC
> Reporter: Lou DeGenaro
> Assignee: Lou DeGenaro
> Priority: Minor
>
> Recently, a job was submitted but got stuck in state "Completing". All work
> items had completed. During the run a Job Process (JP) was launched and got
> stuck in Initializing state because the machine on which it (once) existed
> crashed and (therefore) the DUCC Agent responsible was unable to report or
> take action. This stuck JP was keeping the job from advancing to the
> "Completed" state.
> The user issued the DUCC cancel command using flag --dpid to cancel the bogus
> JP and the job completed normally.
> This situation could be detected by the orchestrator (OR) and handled w/o
> human (user) intervention.
> Additionally, the WS could be helpful in a) identifying those cases that
> cannot be automatically handled and b) offering guidance towards freeing up
> work items held in limbo.
