HDFS is = a filesystem that is designed to support map-reduce computation. =A0As such= , the semantics differ from what SVN or GIT would want to have.

HBase provides versioned values. =A0= That might suffice for your needs.

HDFS is merely a filesystem today. You'll need to write = your own versioning layer on top of it if you need such a functionality.
