Abhishek Singh Chouhan commented on HBASE-18374:
------------------------------------------------
The test failures are unrelated. However it looks like we have unstable tests
(i ran hadoop.hbase.security.access.TestAccessController3 on branch-1 and the
failure is reproducible in a few runs). I'll create a jira for the flakyness if
one's not already there. Looks to be related to HBASE-16488 that went in a
couple o days ago from the first look at test failure logs. [~apurtell] Should
i go ahead and commit this if there are no objections?

> At the RS level we have latency metrics for mutate/puts and deletes that are
> updated per batch (ie. at the end of entire batchop if it contains put/delete
> update the respective metric) in contrast with append/increment/get metrics
> that are updated per op. This is a bit ambiguous since the delete and put
> metrics are updated for multi row mutations that happen to contain a
> put/delete. We should rename the metric(eg. delete_batch)/add better
> description. Also we should add metrics for single delete client operations
> that come through RSRpcServer.mutate path. We should also add metrics for
> checkAndPut and checkAndDelete.
