[jira] [Created] (STORM-3053) blobstores deleted before topologies can be submitted

Aaron Gresch created STORM-3053:
-----------------------------------

             Summary: blobstores deleted before topologies can be submitted
                 Key: STORM-3053
                 URL: https://issues.apache.org/jira/browse/STORM-3053
             Project: Apache Storm
          Issue Type: Bug
    Affects Versions: 2.0.0
            Reporter: Aaron Gresch
            Assignee: Aaron Gresch


We have integration tests failing that create a blobstore and then fail to submit a topology.  Digging into the logs, it looks like there is a nimbus thread that runs every 10 seconds and deletes blobstores if there is no associated topology.  We're hitting a race between the two calls periodically.  

 

 

A possible fix could be to save the timestamp when the blobstore AtomicOutputStream closes and give some grace period before cleaning up based on this timestamp.
