             Summary: Blob localization time-outs can cause Slot to be stuck 
and leaked over time
                 Key: STORM-3254
                 URL: https://issues.apache.org/jira/browse/STORM-3254
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-server
            Reporter: Kishor Patil
            Assignee: Kishor Patil


If Blobs requested by slot take forever to come back, the Slot could get stuck 
in  _waiting-for-blob-localization_ state, even after release of slot or 
topology being killed making that slot unusable. So worker for next assignment 
will never be launched.

The steps to reproduce this are:
 # Delay blob store localization.
 # kill topology and check jstack.
 #  worker will not be scheduled.
