Arpit Agarwal updated HADOOP-9527:
----------------------------------
Attachment: RenameLink.java
This test is exposing a Java 1.6 bug on Windows when trying to rename a
symlink. Attached a minimal repro to demonstrate the JVM bug.
Here is the output on Windows using Java 1.7 and 1.6. 1.7 renames the symlink
as expected, while 1.6 renames the target of the symlink.

> Key: HADOOP-9527
> URL: https://issues.apache.org/jira/browse/HADOOP-9527
> Project: Hadoop Common
> Issue Type: Bug
> Components: test
> Affects Versions: 3.0.0
> Reporter: Arpit Agarwal
> Fix For: 3.0.0
>
> Attachments: RenameLink.java
>
>
> 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.
