Need Help with HDFS Build Failure
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,

Hi Aaron,
Thanks for your reply,
The build looks like its working now
(I had to do a fresh checkout however)
I hope to be able to learn enough to eventually be able
to contribute back to this project.
Thanks,
Amit

This was because a commit to common yesterday temporarily broke the HDFS
build while we were waiting for an associated HDFS patch to be committed.
That commit happened earlier today, so HDFS should be back to building
correctly.
Sorry for the trouble in the interim.
