Subject [jira] [Commented] (HDFS-11224) Lifeline message should be ignored for dead nodes
Date Fri, 09 Dec 2016 06:23:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15734475#comment-15734475
] 

Vinayakumar B commented on HDFS-11224:
--------------------------------------

Thanks [~anu] for review. 
HDFS-9911, is not related to this fix. Current fix just avoids the effect of RPC, but cannot
avoid the RPC itself, which increments the Metric value asserted in HDFS-9911's failure.
So, I commented the possible reason of failure in HDFS-9911 itself. Please check.
I will commit this Jira shortly.

of node.
