Chris Nauroth updated HADOOP-12055:
-----------------------------------
       Resolution: Fixed
    Fix Version/s: 2.8.0
     Hadoop Flags: Reviewed
           Status: Resolved  (was: Patch Available)

+1 for the patch.  I tested it on Windows.  I have committed this to trunk and 
branch-2.  Thank you for the contribution, Andrew.

I'm sorry for the delay.  I ran into some problems with 
{{TestDatanodeLayoutUpgrade}}.  Those problems turned out to be unrelated to 
this patch, so I filed a new patch on HDFS-8554 to fix it.

bq. I don't have a Windows dev environment.

All Apache committers have been offered a free MSDN license.  The details are 
documented here.

https://svn.apache.org/repos/private/committers/donated-licenses/msdn-license-grants.txt

After getting the free MSDN license, you can download the installation iso for 
Windows Server 2008 or 2010 and run it in a VirtualBox VM (or your hypervisor 
of choice).  Instructions for setting up a Windows development environment have 
been in BUILDING.txt for a few years.

This would prevent situations where patches are blocked from getting committed 
while waiting for me or any other individual to test.  I'm not sure if the MSDN 
license information is widely known, so I'll send a reminder on the dev mailing 
lists.

> Since our min version is now JDK7, there's hardlink support via {{Files}}. 
> This means we can deprecate the JNI implementation and discontinue usage.
