Arpit Agarwal commented on HADOOP-9527:
---------------------------------------
The test failure looks unrelated to my patch. The exception indicates a
NameNode bug.

> Multiple test cases are broken. I didn't look at each failure in detail.
> The main cause of the failures appears to be that RawLocalFS.readLink() does
> not work on Windows. We need "winutils readlink" to fix the test.
