Subject [jira] [Commented] (HBASE-17816) HRegion#mutateRowWithLocks should update writeRequestCount metric
Date Fri, 24 Mar 2017 00:26:41 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15939483#comment-15939483

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.

> 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.
