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)
> Capacity reported in some of the commands is not consistent with the Web UI
> reported data
