Eric Yu commented on HBASE-8483:
--------------------------------
[~ted_yu] The 0.94 branch passes tests locally with patch applied.
[[email protected]] Oh, synchronizing on masterAndZKLock would be better and
less confusing. I didn't notice the change in synchronization from 0.94 to
0.95. In 0.94, synchronization is on the getZooKeeperWatcher method and there
wasn't a separate closeZooKeeperWatcher method. I can modify the trunk patch.
Maybe I can take out the synchronization I added to internalClose if I move
this.closed = true; before closeZooKeeperWatcher().
