churro morales updated HBASE-15727:
-----------------------------------
Attachment: HBASE-15727.patch
I just time getData() for the base znode? Even though an exists() call is
made. I was torn whether to time both, but thought getData() would be a better
measure.

> It would be nice to have the canary tool also monitor zookeeper. Something
> simple like doing a getData() call on zookeeper.znode.parent
> It would be nice to create clients for every instance in the quorum such that
> you could monitor overloaded or poor behaving instances.
