Chris Nauroth updated HADOOP-8973:
----------------------------------
Attachment: HADOOP-8973-branch-trunk-win.2.patch
I'm attaching an updated patch.
{quote}
We should skip this call on Windows if it is known to be broken.
{quote}
Each check in the new patch now has this form: if (Windows) then do special
check else do File.canRead/canWrite/canExecute, so we bypass the broken File
APIs on Windows but still use them on Linux where they are known to work
correctly.

Does this change the current directory of the calling process?
{quote}
I added a comment explaining that it launches a separate process and does not
change the working directory of the current process.
Thanks!
