>  'NON DFS Used' value  in Services -> HDFS -> Summary if different from the Value
shown in NameNode UI (see Picture).
> in NAMENODE UI -->
> !https://issues.apache.org/jira/secure/attachment/12901501/namenode.png!
> In Services -> HDFS -> Summary
> !https://issues.apache.org/jira/secure/attachment/12901499/ambari-2.png!
> In NameNode UI the Non DFS Used is taken from 'NonDfsUsedSpace' variable from  REST API
call : http://host1:50070/jmx?qry=Hadoop:service=NameNode,name=NameNodeInfo 
> Where host1 is the Name Node Server FQDN
> but in Ambari we are calculating the same value from (Total Allocated - DFS USed - DFS
Remaining) .
> due to which this issue is happening.
> as a Fix we need to use the 'capacityNonDfsUsed' which comes from Server in NameNode
metrics
> 'FSNamesystem > CapacityNonDFSUsed'
> attached the patch in the JIRA.
> Please fix this bug
