Subject [jira] [Commented] (HDFS-4114) Deprecate the BackupNode and CheckpointNode in 2.0
Date Mon, 05 Nov 2012 18:24:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13490789#comment-13490789
] 

Suresh Srinivas commented on HDFS-4114:
---------------------------------------

In federation, we wanted to use CheckpointNode for sharing a single checkpointer for all the
namenodes in a cluster, triggered based on crontab. I have not had time to explore this further.

Looking at the discussion so far, I understand removing/deprecating if no one plans to use
or work on BackupNode. Given that Konstantin has indicated interest in pursuing it, I would
leave it as it is right now. Konstantin, it would be great if you can share your plans and
timelines. Meanwhile, for next few months, if any issues crop up, I volunteer to spend my
time fixing them.
