It's because this patch imports hadoop metrics dependencies into hbase-client
for the first time. Attaching an amended patch that gets the test to pass.

> Consider adding instrumentation to RecoverableZooKeeper that exposes metrics
> on the performance and health of the embedded ZooKeeper client: latency
> histograms for each op type, number of reconnections, number of ops where a
> reconnection was necessary to proceed, number of failed ops due to
> CONNECTIONLOSS, number of failed ops due to SESSIONEXIPRED, number of failed
> ops due to OPERATIONTIMEOUT.
> RecoverableZooKeeper is a class in hbase-client so we can hook up the new
> metrics to both client- and server-side metrics reporters. Probably this
> metrics source should be a process singleton.
