Bikas Saha commented on HADOOP-8973:
------------------------------------
I synced offline with Arpit. I now see why the implies may be incorrect for
scenarios you mention. In that case, I would really like this patch to fix the
other broken checkDir also because that is incorrect too and it doesnt make
sense to fix the same bug in 2 patches. This would also need to be backported
to branch-1.

> check if a directory is inaccessible. These APIs are not reliable on Windows
> with NTFS ACLs due to a known JVM bug.
