[~ctubbsii] since you were just digging in thrift, do you have any insight on this?

> Key: ACCUMULO-2848
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2848
> Project: Accumulo
> Issue Type: Bug
> Components: tserver
> Affects Versions: 1.5.1, 1.6.0
> Reporter: Josh Elser
> Priority: Minor
> Fix For: 1.5.2, 1.6.1, 1.7.0
>
>
> In trying to get the tserver to shut down cleanly for ACCUMULO-2739, I noticed:
> {code}
> public static void stopTServer(TServer s) {
> if (s == null)
> return;
> s.stop();
> try {
> Field f = s.getClass().getDeclaredField("executorService_");
> f.setAccessible(true);
> ExecutorService es = (ExecutorService) f.get(s);
> es.shutdownNow();
> } catch (Exception e) {
> TServerUtils.log.error("Unable to call shutdownNow", e);
> }
> }
> {code}
> In Thrift 0.9.0, the {{executorService_}} doesn't appear to exist anymore on the implementation of TServer we're using.
