Subject [jira] [Commented] (CASSANDRA-9871) Cannot replace token does not exist - DN node removed as Fat Client
Date Thu, 23 Jul 2015 12:45:06 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14638741#comment-14638741
] 

Jason Brown commented on CASSANDRA-9871:
----------------------------------------

[~Stefania] can you provide a dump of both nodetool gossipinfo and nodetool status? {{isFatClient}}
returns true as the endpoint is not a member in TokenMetadata, and that's why we fail in {{SS.joinTokenRing}}
(we check to see if the token is associated with a TokenMetadata member).

> We lost a node due to disk failure, we tried to replace it via -Dcassandra.replace_address
per -- http://docs.datastax.com/en/cassandra/2.1/cassandra/operations/opsReplaceNode.html
> The node would not come up with these errors in the system.log:
> {code}
> INFO  [main] 2015-07-22 03:20:06,722  StorageService.java:500 - Gathering node replacement

> INFO  [GossipTasks:1] 2015-07-22 03:22:59,300  Gossiper.java:735 - FatClient /10.171.115.233
has been silent for 30000ms, removing from gossip
> ERROR [main] 2015-07-22 03:23:28,485  CassandraDaemon.java:541 - Exception encountered

> java.lang.UnsupportedOperationException: Cannot replace token -1013652079972151677 which
does not exist!
> {code}
> It is not clear why Gossiper removed the node as a FatClient, given that it was a full
node before it died and it had tokens assigned to it (including -1013652079972151677) in system.peers
and nodetool ring.
