Chris Nauroth commented on HDFS-6572:
-------------------------------------
I think I'll put it into trunk and branch-2, since it's not directly related to
the encryption work. That will keep the merge patches smaller too when it
comes time for merging the encryption work. I'll plan to do this by end of day
unless I hear otherwise from you.
> Add an option to the NameNode that prints the software and on-disk image
