Todd Lipcon commented on HDFS-3095:
-----------------------------------
I kind of disagree. Mount points should not be in directories that are writable
by the hdfs user.... and making the user mkdir all of the storage dirs before
running the NN format is pretty unfriendly.
> Namenode format should not create the storage directory if it doesn't exist
