Lei Xia created HELIX-618:
-----------------------------

             Summary:  Job hung if the target resource does not exist anymore 
at the time when it is scheduled.
                 Key: HELIX-618
                 URL: https://issues.apache.org/jira/browse/HELIX-618
             Project: Apache Helix
          Issue Type: Bug
            Reporter: Lei Xia
            Assignee: Lei Xia


 When the job gets scheduled, if the target resource does not exist any more 
(for example, database already deleted but the backup job is still there), the 
job is stuck and all the rest of jobs in the same workflow are stuck.

Solution:

If the target resource of a job does not exist, the job should be failed 
immediately. And depends on the queue configuration, the rest of jobs will 
either continue to run, or the queue will be marked as failed.
