[jira] [Commented] (CASSANDRA-5337) vnode-aware replacenode command

    [ https://issues.apache.org/jira/browse/CASSANDRA-5337?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13748022#comment-13748022 ] 

Mike Heffner commented on CASSANDRA-5337:
-----------------------------------------

Is it correct that these two conditionals should be updated with the same method:

(another case later in patch)

It would seem like one of those should be {{!DatabaseDescriptor.isReplacing()}}.

Apologies if I'm reading this wrong, just looked wrong on initial read.

> Currently you have the following options to replace a dead, unrecoverable node:
> - replacetoken.  this requires specifying all 256 or so vnode tokens as a CSL
> - bootstrap new node, decommission old one.  this is inefficient since the new node's vnodes will probably not overlap much with the old one's, so we replicate stream about 2x as much as if we were just replacing the old with the new
> We should add an analogue to replacetoken that takes the address or node ID of the dead node instead.
