------------------------------------

             Summary: failure node rejoin
                 Key: CASSANDRA-12955
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12955
             Project: Cassandra
          Issue Type: Bug
          Components: Streaming and Messaging
         Environment: Cassandra 2.2.8
Amazon Linux AMI 2016.03
            Reporter: Yuji Ito
            Priority: Minor


A failure node can rejoin a cluster after killing all nodes and restarting a seed node.

Failure node is a node whose Cassandra data (/var/lib/cassandra) is removed.
The failure node is refused to rejoin the cluster without killing & restarting other nodes because its address already exists.
However, it is possible to rejoin the cluster after killing all nodes and restarting seed nodes.

*cluster*:
* C* 2.2.8
* a cluster has node1, 2, 3
* node1 is a seed
* replication_factor: 3

*how to*:
# stop C* process and delete all data in /var/lib/cassandra on node2 ($sudo rm -rf /var/lib/cassandra/*)
# stop C* process on node1 and node3
# restart C* on node1
# restart C* on node2

Node 2 (failure node) can rejoin the cluster at 4):
