Description

We ran into HBASE-26575 recently, but had a hard time tracking down where the edits were coming from. The only real evidence of a failure in replication was the ageOfLastShipped metric and some warnings in the logs. It would be nice to add an explicit metric around source.failedBatches and sink.failedBatches, incremented whenever an exception is encountered.
