> In HDFS, following roles are supported in NameNodeRole: ACTIVE, BACKUP, 
> CHECKPOINT and STANDBY.
> Active and Standby are the state of the NameNode. While Backup and CheckPoint 
> are the name/role of the daemons that are started. This mixes up the run time 
> state of NameNode with the daemon role. I propose changing the NameNodeRole 
> to: NAMENODE, BACKUP, CHECKPOINT. HDFS-1974 will introduce the states active 
> and standby to the daemon that is running in the role NAMENODE.
