Suresh Srinivas updated HDFS-5662:
----------------------------------
Description:
A datanode can't be decommissioned if it has replica that belongs to a file
with a replication factor larger than the rest of the cluster size.
One way to fix this is to have some kind of minimum replication factor setting
and thus any datanode can be decommissioned regardless of the largest
replication factor it's related to.
