Nitay Joffe updated HBASE-1596:
-------------------------------
Attachment: hbase-1596.patch
This patch removes WatcherWrapper, forcing all users of ZooKeeperWrapper to
pass in a Watcher at construction time. This is to better force the users of
the class to handle things like session expired.
Currently the only user of ZooKeeperWrapper that doesn't pass in a Watcher is
the Master. This adds an empty one. There is a separate jira, HBASE-1575, to
handle session expired on the master. The rest (RegionServer, TableServers) are
already passing in a watcher and handling session expired.
> Remove WatcherWrapper and have all users of ZooKeeperWrapper supply a Watcher.

> We originally wrote a WatcherWrapper for our ZooKeeperWrapper which cuts
> through some of the ZooKeeper interface so that we wouldn't have to supply
> Watchers everywhere. Now that we're having to deal with things like Session
> Expired all over the place, this class should no longer be used.
