Subject [jira] Commented: (HADOOP-2816) Cluster summary at name node web has confusing report for space utilization
Date Thu, 18 Sep 2008 23:24:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12632444#action_12632444

Hairong Kuang commented on HADOOP-2816:
---------------------------------------

Suresh, could you please also change the command line cluster report? This is an extra work,
but I think it is better to make the command line report and web UI report to be consistent
in one release. Please take a look at DFSAdmin.report() and DatanodeInfo.getDatanodeReport().
Thanks.

> 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.
