We didn't move any of this to the spring-xd-hadoop, just removed what was in spring-xd-extension-hdfs which was code related to the new datastore support we are building. This code is now in spring-data-hadoop so no need for this project.

Moving what is in spring-xd-hadoop to an extension project is a separate matter - maybe that should be step to in this process. I'll create a spring-xd-extension-hadoop project so we can get rid of the code that is currently in spring-xd-hadoop
