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.
