+1. Backporting this does not in any way impact the release of 21.

+1. Although this is a new feature, I'd like to have it committed to 0.21
since we have so many issues with delayed decomission recently.

time to complete.

Hi,
We will be committing some changes to the Namenode Health page
(dfshealth.jsp) as part of the fix in HDFS-758. This will enable us to
monitor the progress of decommissioning of datanodes more effectively.
Summary of changes :
1. A new link on the page for Decommissioning nodes.
2. This link will point to a new page with details about decommissioning
status for each node which include
a) Number of under-relplicated blocks in the node.
b) Number of blocks with only no live replica (i.e. All its replicas
are on decommissioning nodes).
c) Number of under-replicated blocks in open files.
d) Time since decommissioning started.
3. The main page will also contain total number of under-replicated
blocks
in the cluster.
Thanks
jitendra
