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 ?
