Josh Elser commented on ACCUMULO-3139:
--------------------------------------

The downside here is that we have to reflect to get at the pid inside of UNIXProcess, but I don't think that's the end of the world. We could exec out to some bash to try to guess, but that would be error prone too.

> BalanceAfterCommsFailureIT does a SIGSTOP and then SIGCONT to simulate some network outage. It uses pkill to send the signals which will send that to any processes on the system matching "TabletServer".
> This isn't really ideal (and I believe is actually error prone if there is a TabletServer running on the same node by a different user). Figuring out a way to target only the TabletServers running in the minicluster for this test is much better.
