             Summary: Safety check on node joining cluster (based on last seen vs GC grace period) to avoid zombie data
                 Key: CASSANDRA-6257
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6257
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Johnny Miller
            Priority: Minor


When a node is rejoining a cluster, it would be nice to have some form of safety check that the cluster recognises the last time the node was part of the cluster is greater that the GC grace period and therefore should not be able to rejoin the cluster unless the administrator specifically requests it.

The goal of this is to help avoid the potential issues with deleted data coming back from the rejoining nodes dataset.
