Subject [jira] Commented: (CASSANDRA-2160) Add "join" command to the nodetool
Date Mon, 28 Feb 2011 10:35:36 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2160?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13000209#comment-13000209

Sylvain Lebresne commented on CASSANDRA-2160:
---------------------------------------------

bq. This helps you to return node to the ring after decommission or if it haven't joined the
ring at startup without restarting application.

Ok for joining the ring if -Djoin_ring=false was used at startup. But then SP.joinRing() should
be called. This is exposed through JMX but not nodetool and I do agree that it should.

As for rejoining after decommission, I don't see the point. You're not supposed to decommission
a node for no reason. I'm not confortable adding code that isn't clearly useful.
