Subject Re: build and use hadoop-git

Start with hadoop-common to start building .

hadoop-hdfs / hadoop-mapred pull the dependencies from apache snapshot 
repository that contains the nightlies of last successful builds so in 
theory all 3 could be built independently because of the respective 
snapshots being present in apache snapshot repository.

If you do want to make cross-project changes and test them -
* create a local ivy resolver and
* place it before the apache snapshot in the ivy settings .
* publish the jar for a given project to the directory pointed by the 
ivy resolver in step 1
* clear ivy cache
* recompile.
