Konstantin Shvachko commented on HDFS-2141: ------------------------------------------- I disagree with this change. NAMENODE is not a role. All of them are NameNodes. The role is active, checkpoint, or standby. I also do not understand what is the long term purpose of the change. I think the HA work should be done in a branch. Getting up to speed after vacation, Sorry if I missed any discussions in last two weeks. > Remove NameNode roles Active and Standby (they become states) > ------------------------------------------------------------- > > Key: HDFS-2141 > URL: https://issues.apache.org/jira/browse/HDFS-2141 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: name-node > Reporter: Suresh Srinivas > Assignee: Suresh Srinivas > Fix For: 0.23.0 > > Attachments: HDFS-2141.1.patch, HDFS-2141.patch > > > 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. -- This message is automatically generated by JIRA.
