--------------------------
    Attachment: 0001-12376-HBaseAdmin-leaks-ZK-connections-if-failure-sta.patch

Patch for 0.98.

Don't have issue in master/branch-1.

Opened up CatalogTracker some so I could inject failure for a unit test.

Reviews please.  Locally 0.98 TestAdmin passes.

> This is a 0.98 issue that some users have been running into mostly running Canary and
for whatever reason, setup of zk connection fails, usually with a ConnectionLossException.
 End result is ugly leak zk connections.  ZKWatcher created instances are just left hang out.
