             Summary: Add a metric to show the locality of ssd in table.jsp
                 Key: HBASE-24038
                 URL: https://issues.apache.org/jira/browse/HBASE-24038
             Project: HBase
          Issue Type: Improvement
          Components: monitoring
            Reporter: Zheng Wang
            Assignee: Zheng Wang

If a hdfs block has a replica on local hdd and a replica on remote ssd, then 
the local one is first priority, so i think it is useful to show the locality 
of ssd, especially when use the ONE_SSD storagy policy.
I have developed a patch, will submit it later.
