Subject [jira] [Created] (HBASE-9604) Add metric on short-circuit reads

stack created HBASE-9604:
----------------------------

             Summary: Add metric on short-circuit reads
                 Key: HBASE-9604
                 URL: https://issues.apache.org/jira/browse/HBASE-9604
             Project: HBase
          Issue Type: Task
          Components: metrics
            Reporter: stack


Got this from a Colin message this afternoon:

"There are HDFS statistics that HBase could be checking by calling DFSInputStream#getReadStatistics.
 This tells you how many of your reads have been remote, local, short-circuit, etc.  You could
file an HBase JIRA for them to roll those up into the HBase stats. Seems like a good idea
to me."
