Lou DeGenaro updated UIMA-2642:
-------------------------------
Component/s: DUCC
> DUCC should provide job cancel by proxy capability
> --------------------------------------------------
>
> Key: UIMA-2642
> URL: https://issues.apache.org/jira/browse/UIMA-2642
> Project: UIMA
> Issue Type: Improvement
> Components: DUCC
> Reporter: Lou DeGenaro
> Assignee: Lou DeGenaro
>
> Presently, DUCC job submit provides the ability to wait for job completion
> before exiting via the --wait_for_completion flag, and to automatically
> cancel the job when ctrl-C is invoked via the --cancel_job_on_interrupt flag.
> In the case where the submit+monitor CLI combination is terminated by, say,
> kill -9 the job is (unfortunately) not automatically canceled.
> To remedy this deficiency, the DUCC webserver (WS) will act as proxy to
> receive periodic "I am alive" requests from the submit+monitor CLI, and if
> these requests cease to arrive for some ducc.properties configured interval,
> then the job is auto-canceled.
