Chris Nauroth commented on HADOOP-9413:
---------------------------------------

Ivan, I just uploaded a new patch on HADOOP-9290.  Can you try running with that to see if it resolves the test failures you saw with HADOOP-9413?

> So far, we've seen many unittest and product bugs in Hadoop on Windows because Java's APIs that manipulate with permissions do not work as expected. We've addressed many of these problems on one-by-one basis (by either changing code a bit or disabling the test). While debugging the remaining unittest failures we continue to run into the same patterns of problems, and instead of addressing them one-by-one, I propose that we expose a set of equivalent wrapper APIs that will work well for all platforms.
> Scanning thru the codebase, this will actually be a simple change as there are very few places that use File#setReadable/Writable/Executable and File#canRead/Write/Execute (5 files in Common, 9 files in HDFS).
> HADOOP-8973 contains additional context on the problem.
