[jira] [Created] (CASSANDRA-14742) Race Condition in batchlog replica collection

Alex Petrov created CASSANDRA-14742:
---------------------------------------

             Summary: Race Condition in batchlog replica collection
                 Key: CASSANDRA-14742
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14742
             Project: Cassandra
          Issue Type: Test
            Reporter: Alex Petrov
            Assignee: Alex Petrov


When we collect nodes for it in StorageProxy#getBatchlogReplicas, we already filter out down replicas; subsequently they get picked up and taken for liveAndDown.

There's a possible race condition due to picking tokens from token metadata twice (once in StorageProxy#getBatchlogReplicas and second one in RP#forBatchlogWrite)
