[GitHub] [cassandra] josh-mckenzie opened a new pull request, #1797: Cassandra 17830 - Protect against Gossip backing up due to a quarantined endpoint without version information

josh-mckenzie opened a new pull request, #1797:
URL: https://github.com/apache/cassandra/pull/1797

   In [CASSANDRA-16759](https://issues.apache.org/jira/browse/CASSANDRA-16759), like we changed from iterating over liveMembers + unreachableMembers to all keys in endpointStateMap [here](https://github.com/apache/cassandra/commit/2fba5c80ce7bf71d04c62043ffa1088b9e832d83#diff-99267a2170b04fd7dd24d6c6bf2ba1fc26d6dc896cd74f8c5bd56c476e2540e4R208).
   
   We can have an endpoint in quarantine (in justRemovedEndpoints) which has no release version information. In this case we don't memoize the value and instead recalculate the min version for every endpoint for every incoming gossip message... which can be bad.
