Subject [jira] [Commented] (HADOOP-7668) Add a NetUtils method that can tell if an InetAddress belongs to local host
Date Wed, 21 Sep 2011 21:13:09 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13109875#comment-13109875

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
?
