[jira] [Commented] (HBASE-15267) Read requests count metric is increased when Get operation does not return any record

    [ https://issues.apache.org/jira/browse/HBASE-15267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15146829#comment-15146829 ] 

Elliott Clark commented on HBASE-15267:
---------------------------------------

Seems like the metric is correct. It's all about how many gets were issued. It doesn't say gets that returned things. Just number of gets.
The get could have done a lot of IO so we shouldn't ignore that.

> Read requests count is increased when Get operation returns no record by filtering out. In such cases, Get for deleted record, Get for TTL expired record and Get for filtering out.
> So I fixed the bug and added some more test cases for read metrics.
