Brahma Reddy Battula commented on HDFS-7933:
--------------------------------------------
As per versioning rule [here|http://hadoop.apache.org/versioning.html],I think, we should not add incompatible changes to dot and minor releases..?
> fsck should also report decommissioning replicas.

> Fsck doesn't count replicas that are on decommissioning nodes. If a block has all replicas on the decommissioning nodes, it will be marked as missing, which is alarming for the admins, although the system will replicate them before nodes are decommissioned.
> Fsck output should also show decommissioning replicas along with the live replicas.
