This release fixes a problem brought about in .73 where using the --append-cluster-name incorrectly added the cluster name to paths not associated with a user. Eg /users/hive/warehouse-cluster-name vs /users/hive-cluster-name/warehouse.
This release also allows for the creation of a users and groups file. Using this file one can transfer the users and groups created here to compute nodes so they line up. This makes kerberizing the cluster easier.
