Subject [jira] [Updated] (AMBARI-13509) hdfs disk usage metric confusing
Date Wed, 21 Oct 2015 18:16:27 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-13509?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Antonenko Alexander updated AMBARI-13509:
-----------------------------------------
    Description: 
On the hdfs metrics page we have a metric like

{code}
Disk Usage (Remaining)	7.7 TB / 9.8 TB (78.21%)
{code}

This is confusing as the % and 7.7TB is for free. We have remaining in parentheses  but i
think we need to change this. Read quickly i thought for a second that my hdfs was 80% full
so i went to the NN ui to confirm and then realized that its only 20% full. 

change to 

Disk Usage 	458.2 GB / 488.2 GB (93.85% remaining)

  was:
