Is there a way we can fix this by using some external dependency files? The 
grafana charts are right - they are getting the ScanTime metrics but the Ambari 
dashboard graphs are wrong as they try to collect the old metric.

> Num Scan Nxt Requests Graph of HBASE-RegionServers Dashboard page is showing
