[jira] [Created] (CASSANDRA-19286) Accord: Safe guards against erroneously marking replicas stale

Benedict Elliott Smith created CASSANDRA-19286:
--------------------------------------------------

             Summary: Accord: Safe guards against erroneously marking replicas stale
                 Key: CASSANDRA-19286
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-19286
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Benedict Elliott Smith


Replicas are marked stale using inferences made when data cannot be obtained from peers. However, if a replica is marked stale erroneously it could cause an outage; any systemic issue in this system could be severe. We should harden this system against potential errors, and offer the option of only marking replicas stale that have been marked as stale by an operator (and otherwise reporting an error to the user).
