------------------------------------

             Summary: NullPointerException in Provenance Repository on startup 
                 Key: NIFI-3186
                 URL: https://issues.apache.org/jira/browse/NIFI-3186
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.1.0
            Reporter: Joseph Gresock
            Assignee: Joseph Gresock
             Fix For: 1.1.1


Often when NiFi restarts itself, we will get this error on startup, which prevents the node from starting until we delete the provenance_repository from disk.
