-As for scan, it is impossible to visit an inexistent row.  But 'Get' could do it because you specify the rowKey, right?-

Sorry for my misunderstanding.  yeah, you are right, [~anoop.hbase],  i am not sure how 'Scan' path it is,  if it goes the same path as 'Get',  the patch currently will miss scan request, right?

> 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.
