Gary Helmling updated HBASE-17578:
----------------------------------
Release Note: In prior versions, the HBase Thrift handlers failed to
increment per-method metrics when an exception was encountered. These metrics
will now always be incremented, whether an exception is encountered or not.
This change also adds exception-type metrics, similar to those exposed in
regionservers, for individual exceptions which are received by the Thrift
handlers.
> Thrift per-method metrics should still update in the case of exceptions

> Currently, the InvocationHandler used to update per-method metrics in the
> Thrift server fails to update metrics if an exception occurs. This causes us
> to miss outliers. We should include exceptional cases in per-method
> latencies, and also look at adding specific exception rate metrics.
