> There are tests in TestBulkWorkflowXCommand which perform bulk killing.
> This might fail sometimes, because the {{externalChildIDs}} is set to
> "00000001-dummy-oozie-wrkf-W " that causes an action to fail:
> {code}
> org.apache.oozie.action.ActionExecutorException: IllegalArgumentException:
> JobId string : 00000001-dummy-oozie-wrkf-W is not properly formed

> {code}
> Since this code runs on a separate thread, it might randomly interfere with
> the main test logic, which expects the job status to be "KILLED", but
> sometimes the ActionKillXCommand has a chance to update it to "FAILED".
> Solution: set a proper (parseable) job id:
> {code}
> action.setExternalChildIDs("job_201601011800_0001");
> {code}
> See
