[jira] [Created] (ACCUMULO-2244) Tracer occasionally hangs on exit

Sean Busbey created ACCUMULO-2244:
-------------------------------------

             Summary: Tracer occasionally hangs on exit
                 Key: ACCUMULO-2244
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2244
             Project: Accumulo
          Issue Type: Bug
          Components: trace
    Affects Versions: 1.4.5
         Environment: 1.4.5-SNAPSHOT on CDH4.5.0 w/gremlins
            Reporter: Sean Busbey
            Priority: Minor


When I am perturbing the availability of network components via gremlins, occasionally a tracer that has lost its zookeeper lock will hang while trying to exit.

There's nothing obvious in the logs. Jstack shows some thrift stuff around.

kill -9 on the process makes it finally exit and then restarting works like normal.

I suspect it's because of me monkeying with iptables (rather than the network failure itself). Combined with the obvious workaround, low priority.

Not sure if it impacts later versions.
