Brahma Reddy Battula commented on HDFS-7933:
--------------------------------------------

bq.Actually can we make this new fsck output configurable, instead of reverting this patch? 
Yes,making it configurable based on extra option from {{fsck}} is better. if you just escape the output,it will be hidden..? Sorry for delayed response.

> 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.
