stack commented on HBASE-19753:
-------------------------------
Did some quick tests this morning. Replacing the wait-on-connect with the
keepalive patch had hbase-zookeeper large tests timeout occasionally. I didn't
dig too much. The keepalive looks like we need it. .008 wraps it in.
I ran some tests this morning on .007, no timeout addendum, and got failures
like below
[ERROR] Tests run: 3, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 159.169

Let me try this combined .008. Running it on cluster machines too though am
less and less inclined to believe results out of these machines.
