-------------------------------------
Summary: Refined ZooKeeperWatcher to prevent ZooKeeper's callback
while construction
Key: HBASE-15292
URL: https://issues.apache.org/jira/browse/HBASE-15292
Project: HBase
Issue Type: Bug
Components: Zookeeper
Reporter: Hiroshi Ikeda
Priority: Minor
The existing code is not just messy but also contains a subtle bug of
visibility due to missing synchronization between threads.
The root of the evil is that ZooKeeper uses a silly anti-pattern, starting a
thread within its constructor, and in practice all the developers are not
allowed to use ZooKeeper correctly without tedious code.
