> This seems to be a regression caused by HBASE-4791 wherein we check if secure zookeeper
is enabled and if so we make use of saslLatch to verify security handshake is completed. But
in the case of MR, we won't be negotiating a secure connection thus we end up waiting forever
for the saslLatch.
> Since the bug the saslLatch workaround is trying to fix (ZOOKEEPER-1437) is already fixed
in zookeeper-3.4.5. Removal of the workaround fixes the problem.
