LGTM.
Just one question. In the following change in patch-2
{code}
@@ -136,7 +137,7 @@ public void testZKClientRetry() throws Exception {
TestZKClient zkClientTester = new TestZKClient();
final String path = /test;
YarnConfiguration conf = new YarnConfiguration();
-conf.setInt(YarnConfiguration.RM_ZK_TIMEOUT_MS, 1000);
+conf.setInt(YarnConfiguration.RM_ZK_TIMEOUT_MS, ZK_TIMEOUT_MS);
{code}
The timeout was 1000ms and the ZK_TIMEOUT_MS is also set to 1000. Do you think
this will not cause the timeout issue in future? If unsure, I think setting
ZK_TIMEOUT_MS = 1500 would be a good idea.

RM_ZK_TIMEOUT_MS is for ZK session timeout. IMO, 1000 msec is safe and enough time to keep alive. The test failure is caused by 100 msec timeout in TestZKRMStateStore#getNewZooKeeper() called by ZKRMStateStore#createConnection(). Good news: I ran the test 300 times with patch-2, and confirmed all of them succeeded. Without the patch, the test fails each approx. 50 times.

Not sure if we can do anything but just bump up the default value for the
