Subject [jira] [Created] (CASSANDRA-7350) Decommissioning nodes borks the seed node - can't add additional nodes
Date Tue, 03 Jun 2014 22:17:02 GMT
Steven Lowenthal created CASSANDRA-7350:

             Summary: Decommissioning nodes borks the seed node - can't add additional nodes
                 Key: CASSANDRA-7350
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: Ubuntu using the auto-clustering AMI
            Reporter: Steven Lowenthal

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.
