Hey Chris, This is what I also thought and looking at Mountable HDFS options. I need to check if its buggy. To your other ques : I am building an app which will have TBs of data and require analysis. Now I am using HDFS as a background filesystem and Hbase for database option. To do analysis on the data, I use MR jobs . All this is not provided by NFS. One part of this app include document management in which I wanted to provide version control. This is the usecase I have. May be this helps. ☺

My question is really what do you expect to gain by using HDFS this way (vs NFS or a NAS filer for instance) ?

As such, the semantics differ from what SVN or GIT would want to have. HBase provides versioned values. That might suffice for your needs.

You'll need to write your own versioning layer on top of it if you need such a functionality.
