Aaron T. Myers commented on HDFS-2141:
--------------------------------------
bq. The only concern I have is - the metrics is started with current
NamenodeRole.ACTIVE.
But note that this patch doesn't change the {{description}} (and thus the
result of {{NamenodeRole.toString()}}) for {{NamenodeRole.ACTIVE}}. So, the
metrics should be unaffected from a user's point of view, correct?
bq. We could just have NodeType with NameNode, DataNode, Backup and
Checkpointer?
Exactly.

> 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.
