[jira] [Reopened] (UIMA-2642) DUCC should provide job cancel by
proxy capability
[ https://issues.apache.org/jira/browse/UIMA-2642?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lou DeGenaro reopened UIMA-2642:
--------------------------------
Two small enhancements:
1. make default expiry 10 minutes, instead of 0 minutes (meaning disabled)
2. issue warning at webserver (WS) boot time if its user name (ducc) is not defined in ducc.administrators
> DUCC should provide job cancel by proxy capability
> --------------------------------------------------

> Key: UIMA-2642

> Project: UIMA

> 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.
