---------------------------------------------
Summary: Filter replicas for counter mutation leader to be JOINED
replicas to decouple from RPC_READY state
Key: CASSANDRA-19103
URL: https://issues.apache.org/jira/browse/CASSANDRA-19103
Project: Cassandra
Issue Type: Improvement
Reporter: Stefan Miklosovic
In CASSANDRA-18935, what I did was that if transport is turned off while node
is up, it will set RPC_READY to "false". Before 18935 was in, if you turned off
transport, RPC_READY was not changed to true but it stayed to be "true" for
ever.
Clearly, this was wrong, so I fixed that, but when I did that, the code which
decides who will be the leader of counter mutation was broken, because that
node filtered out all nodes for which RPC_READY is false, which never happened
before, because nobody has set it to "false" on turned off transport.
So, we decided to revert this regression in 5.0-rc1 and I was waiting for
CEP-21 to be in because I saw it is rewritten there with TODO to filter JOINED
nodes.
Hence, we can decouple this logic and fix RPC_READY status finally.
