> 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
> Attachments: ACCUMULO-2244.patch, tracer_18017.debug.log,
> tracer_18017.jstack.txt, tracer_18017.out
>
>
> 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.
