Masashi Ozawa commented on CASSANDRA-7350: ------------------------------------------ It's still happening in 2.0.11 for me. Filed CASSANDRA-8422. > Decommissioning nodes borks the seed node - can't add additional nodes > ---------------------------------------------------------------------- > > Key: CASSANDRA-7350 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7350 > Project: Cassandra > Issue Type: Bug > Components: Core > Environment: Ubuntu using the auto-clustering AMI > Reporter: Steven Lowenthal > Assignee: Shawn Kumar > Priority: Minor > Labels: qa-resolved > Fix For: 2.0.9 > > > 1) Launch a 4 node cluster - I used the auto-clustering AMI (you get nodes > 0-3) > 2) decommission that last 2 nodes (nodes , leaving a 2 node cluster) > 3) wipe the data directories from node 2 > 4) bootstrap node2 - it won't join "unable to gossip with any seeds". > If you bootstrap the node a second time, it will join. However if you try to > bootstrap node 3, it will also fail. > I discovered that bouncing the seed node fixes the problem. I think it > cropped up in 2.0.7. > Error: > ERROR [main] 2014-06-03 21:52:46,649 CassandraDaemon.java (line 497) > Exception encountered during startup > java.lang.RuntimeException: Unable to gossip with any seeds > at org.apache.cassandra.gms.Gossiper.doShadowRound(Gossiper.java:1193) > at > org.apache.cassandra.service.StorageService.checkForEndpointCollision(StorageService.java:447) > at > org.apache.cassandra.service.StorageService.prepareToJoin(StorageService.java:656) > at > org.apache.cassandra.service.StorageService.initServer(StorageService.java:612) > at > org.apache.cassandra.service.StorageService.initServer(StorageService.java:505) > at > org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:362) > at > org.apache.cassandra.service.CassandraDaemon.activate(CassandraDaemon.java:480) > at > org.apache.cassandra.service.CassandraDaemon.main(CassandraDaemon.java:569) > ERROR [StorageServiceShutdownHook] 2014-06-03 21:52:46,741 > CassandraDaemon.java (line 198) Exception in thread Thread[StorageServi -- This message was sent by Atlassian JIRA (v6.3.4#6332)
