Brian Bockelman commented on HDFS-758:
--------------------------------------

This would be incredibly useful for our site.  We find that there are sometimes 
very "long tails" in decommissioning - the last 4 hours of a node 
decommissioning might be due to a handful of stuck or slow blocks.  It drives 
our admins nuts that they don't know if things are 50% done or 99.999% done 
(and should just pull the plug).

> Improve reporting of progress of decommissioning
