Subject [jira] [Commented] (HDFS-11224) Lifeline message should be ignored for dead nodes
Date Thu, 08 Dec 2016 17:39:58 GMT

Anu Engineer commented on HDFS-11224:
-------------------------------------

[~vinayrpet] Thanks for catching this and providing a patch. The patch looks very good. I
wanted to flag a related race condition that is reported in HDFS-9911. Please look at the
last comment -- Which explains how to simulate that issue.  If this patch fixes that issue
too, would it make sense to add it as part of test cases ?  if not, do you think it makes
sense to fix it via this JIRA ?

of node.
