Subject [jira] Updated: (HADOOP-4281) Capacity reported in some of the commands is not consistent with the Web UI reported data
Date Mon, 29 Sep 2008 23:10:45 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4281?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Suresh Srinivas updated HADOOP-4281:

    Release Note: 
Changes made (See corresponding Web UI change in 2816), to the command "hadoop dfsadmin -report".
The following changes are made for both Namenode and Datanode reports:
- "Total raw bytes" is changed to "Configured Capacity". Previously this data included the
disk space for all the data directories. Now it excludes reserved space configured using dfs.datanode.du.reserved
config param.
- "Present Capacity" is newly added to indicate the present capacity of the DFS. This is sum
of the remaining and used capacity.
- "Remaining raw bytes" is changed to "DFS Remaining"
- "Used raw bytes" is changed to "DFS Used"
- "% used" is changed to "DFS Used%". It is the percentage of used capacity over "Present
Capacity" instead of "Total raw bytes".
    Hadoop Flags: [Incompatible change, Reviewed]
          Status: Patch Available  (was: Open)
