--------------------------------------------------
Summary: Accord: Harden Node.Id handling: graceful restart for
left nodes, and ensure don’t cause problems with IP reuse
Key: CASSANDRA-19357
URL: https://issues.apache.org/jira/browse/CASSANDRA-19357
Project: Cassandra
Issue Type: Improvement
Components: Accord
Reporter: Benedict Elliott Smith
We rely on TCM for mapping node.id to replicas/IPs, but TCM is not
Accord-epoch-aware, so it might erase a mapping before Accord is finished with
it (and so, after a reboot Accord may not be able to find it again), but also
might permit an IP to be re-used for a new Node.Id when Accord is still using
it for an older epoch.
