David Strauss commented on CASSANDRA-3736: ------------------------------------------ Alternatively, it would be good for Cassandra to provide a convenient (nodetool) way to drop the "Down" IP when a token is simultaneously occupied by one "Up" IP and at least one "Down" IP. > -Dreplace_token leaves old node (IP) in the gossip with the token. > ------------------------------------------------------------------ > > Key: CASSANDRA-3736 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3736 > Project: Cassandra > Issue Type: Bug > Components: Core > Affects Versions: 1.0.0 > Reporter: Jackson Chung > Assignee: Vijay > Fix For: 1.0.7 > > > https://issues.apache.org/jira/browse/CASSANDRA-957 introduce a > -Dreplace_token, > however, the replaced IP keeps on showing up in the Gossiper when starting > the replacement node: > {noformat} > INFO [Thread-2] 2012-01-12 23:59:35,162 CassandraDaemon.java (line 213) > Listening for thrift clients... > INFO [GossipStage:1] 2012-01-12 23:59:35,173 Gossiper.java (line 836) Node > /50.56.59.68 has restarted, now UP > INFO [GossipStage:1] 2012-01-12 23:59:35,174 Gossiper.java (line 804) > InetAddress /50.56.59.68 is now UP > INFO [GossipStage:1] 2012-01-12 23:59:35,175 StorageService.java (line 988) > Node /50.56.59.68 state jump to normal > INFO [GossipStage:1] 2012-01-12 23:59:35,176 Gossiper.java (line 836) Node > /50.56.58.55 has restarted, now UP > INFO [GossipStage:1] 2012-01-12 23:59:35,176 Gossiper.java (line 804) > InetAddress /50.56.58.55 is now UP > INFO [GossipStage:1] 2012-01-12 23:59:35,177 StorageService.java (line 1016) > Nodes /50.56.58.55 and action-quick2/50.56.31.186 have the same token > 85070591730234615865843651857942052864.
