Milind Bhandarkar commented on HADOOP-7668:
-------------------------------------------
Suresh, I think you want a check to see if the same file representing a block
is accessible from the client as well as the datanode. (Checking that both
client and datanode is on the same host, is an overly restrictive check. In
some ways, even if both client and datanode are run on the same node, with
chrooted containers, this is an overly general check.) Right ?
