Vinod Kumar Vavilapalli commented on YARN-3468:
-----------------------------------------------
What do you mean by NM flapping?
You shouldn't really be setting yarn.nodemanager.delete.debug-delay-sec to 10
minute in a production cluster.
Getting this patch in is okay though. Needs a testcase?
> NM should not blindly rename usercache/filecache/nmPrivate on restart
