   @aonishuk  I searched the source code of Apache HBase and the Jira website, and I finally
found this:https://issues.apache.org/jira/secure/attachment/12879158/HBASE-18374.branch-1.001.patch
in [HBASE-18374](https://issues.apache.org/jira/browse/HBASE-18374). 
   I think it involves the **mutate** metrics change:
   ```java
