Ashu Pachauri commented on HBASE-17816:
---------------------------------------
[~Weizhan Zeng] It's matter of semantics, as to what we count as a write
request, a request that was issued or a request that succeeded. If you look at
other parts in the code, we count any request that reaches HRegion, whether
it's successful or not. For example, look at HRegion#batchMutate.
> HRegion#mutateRowWithLocks should update writeRequestCount metric

> Currently, all the calls that use HRegion#mutateRowWithLocks miss
> writeRequestCount metric. The mutateRowWithLocks base method should update
> the metric.
> Examples are checkAndMutate calls through RSRpcServices#multi,
> Region#mutateRow api , MultiRowMutationProcessor coprocessor endpoint.
