-----------------------------------

             Summary: Dashboard: widget for "Disk Usage" should instead show 
disk read/write throughput
                 Key: AMBARI-11414
                 URL: https://issues.apache.org/jira/browse/AMBARI-11414
             Project: Ambari
          Issue Type: Bug
          Components: ambari-metrics
    Affects Versions: 2.1.0
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
            Priority: Critical
             Fix For: 2.1.0


We need HBase "Disk" widget to show disk read/write throughput across all 
RegionServers (currently we are showing disk used %, which doesn't really make 
sense in this context).
This throughput is rate (amount per unit time - MB / sec or whatever unit that 
makes sense)
