Bikas Saha commented on HADOOP-8734:
------------------------------------

So if I understand this right, this fixes a generic deficiency in LocalJobRunner which wasnt showing up because by default files are public to read on Linux FS and so LocalJobRunner would not see issues in accessing private distributed cache from the local FS.
Also, this would make the change to TestMRWithDistributedCache unnecessary?

> It seems that LocalJobRunner does not support private distributed cache. The issue is more visible on Windows as all DC files are private by default (see HADOOP-8731).
