> In HDFS, following roles are supported in NameNodeRole: ACTIVE, BACKUP, CHECKPOINT and
> 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.
