Subject [jira] [Commented] (CASSANDRA-3897) StorageService.onAlive() only schedules hints for joined endpoints
Date Mon, 13 Feb 2012 00:34:59 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3897?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13206585#comment-13206585
] 

Brandon Williams commented on CASSANDRA-3897:
---------------------------------------------

By virtue of not being a ring member, a bootstrapping node can never be hinted for.  That
said, I'm not certain a newly bootstrapped node (that has completed and is a ring member)
will get hint delivery scheduled outside of an onAlive event.

> It seems incorrect to not do hint delivery for nodes that are bootstrapping, as that
would cause sudden spikes in read repair need or inconsistent reads when a node joins the
ring. Particularly if the user is expecting to rely on the new hinted handoff code making
AES much less needed. It would be a POLA violation for bootstrapping nodes to be an exception
to that.
