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.

Hi,
how can I build and use hadoop-git?
The project has recently been split into 3 repositories hadoop-common,
hadoop-hdfs and hadoop-mapred. It's not clear to me how to
build/compile and use the git/tip for the whole framework. E.g. would
building all jars from the 3 subprojects (and copying them under the
same directory) work?
Is there a guide/wiki page out there for this? Or perhaps there is
another repository which still has a centralized trunk for all
subprojects?
thanks in advance,
