Subject [jira] [Created] (TEPHRA-242) Transaction Service sometimes does not shutdown
Date Wed, 16 Aug 2017 18:55:00 GMT
Andreas Neumann created TEPHRA-242:
--------------------------------------

             Summary: Transaction Service sometimes does not shutdown
                 Key: TEPHRA-242
                 URL: https://issues.apache.org/jira/browse/TEPHRA-242
             Project: Tephra
          Issue Type: Bug
          Components: manager
    Affects Versions: 0.12.0-incubating
            Reporter: Andreas Neumann
            Assignee: Andreas Neumann
             Fix For: 0.13.0-incubating


If shutting down encounters an exception (for example, OutOfMemory), it can happen that the
process does not exit. We have observed this after an NPE from DFS (closing the transaction
log), the process stayed alive and the\ prune thread (executor) was not shut down. It was
not clear why the process stayed alive, but it would certainly help to handle exceptions better
in the shutdown sequence.
