Subject [jira] Created: (HADOOP-2816) Cluster summary at name node web has confusing report for space utilization
Date Thu, 14 Feb 2008 02:33:08 GMT
Cluster summary at name node web has confusing report for space utilization
---------------------------------------------------------------------------

                 Key: HADOOP-2816
                 URL: https://issues.apache.org/jira/browse/HADOOP-2816
             Project: Hadoop Core
          Issue Type: Improvement
    Affects Versions: 0.15.3
            Reporter: Robert Chansler


In one example:
Cluster Summary
Capacity	:	1.15 PB
DFS Remaining	:	192 TB
DFS Used	:	717 TB
DFS Used%	:	62 %

Why is Capacity not equal Used plus Remaining?

(The answer is that there is an estimated reserve for local files.)

The presentation should be easily understood by the user.
