Hi, 

I am sorry if this question was asked a lot of times before but I am unable to 
solve my problem. I am trying to build hadoop 0.21.0 from the source. As far as 
my understanding goes, I need to build common, hdfs, and mapred.  I seems to be 
able to build common, but not hdfs and mapred. Here is the error I receive:

Build Failed for HDFS

As far as I understand, I am not offline and I tried to build it using "ant 
clean jar -autoproxy". What can I do to resolve these errors?

Thank you for your time and attention.

Best Regards,
Daniel
