Description

Notice this while setting up a new cluster. Machines have 8 drives. I had made mount locations for the 7 non-root disks, but forgot to mount them. Went through install process, specified these 7 locations for HDFS data directories. Neither Ambari nor HDFS noticed the miss-configuraiton.

Could also be considered an HDFS bug/improvement.
