Hi,
I'm an HDFS newbie. I'm trying to learn more about HDFS by doing a
student project.
Ive been facing build breaks since today with the error messages:

============================================================================================================
Ive tried applying the following patch (posted by Konstantin Boudnik)
https://issues.apache.org/jira/browse/HDFS-1486
to my code , but the build continues to fail.
Also, Is there a way for me to build HDFS while excluding hdfs-test for the
time being?
I'd appreciate any help someone could give me with understanding/resolving
this.
Thanks,
