> When NM restarts frequently due to some reason, a large number of directories like these
left in /data/disk$num/yarn/local/:
> /data/disk1/yarn/local/usercache_DEL_1414372756105
> /data/disk1/yarn/local/usercache_DEL_1413557901696
> /data/disk1/yarn/local/usercache_DEL_1413657004894
> /data/disk1/yarn/local/usercache_DEL_1413675321860
> /data/disk1/yarn/local/usercache_DEL_1414093167936
> /data/disk1/yarn/local/usercache_DEL_1413565841271
> These directories are empty, but take up 100M+ due to the number of them. There were
38714 on the machine I looked at per data disk.
> It appears to be a regression introduced by YARN-661
