Raghu Angadi resolved HADOOP-2147.
----------------------------------

    Resolution: Won't Fix

I thought not removing build dir was more prevalent
convention. Any way, using custom build directory might need
some fixes :


> ant
> ls build
ant  classes  examples                     
hadoop-0.16.0-dev-datajoin.jar 
hadoop-0.16.0-dev-streaming.jar  test
c++  contrib  hadoop-0.16.0-dev-abacus.jar 
hadoop-0.16.0-dev-hbase.jar     src                         
    webapps
------
> ant -Dbuild.dir=buildx
> ls buildx
ant  c++  classes  examples  src  test  webapp



Both builds were successful.

> It would be better if 'ant clean' does not remove build
directory. Many projects do not remove this dir. One
advantage of not removing is that, I can symlink the build
to another place (e.g. /mnt/scratch/) and keep the source
code in more reliable place. I will submit a patch if this
sounds ok.
