             Summary: The way we add or clear failedReplicas may have race
                 Key: HBASE-26449
                 URL: https://issues.apache.org/jira/browse/HBASE-26449
             Project: HBase
          Issue Type: Sub-task
          Components: read replicas
            Reporter: Duo Zhang


We will add a replica to failedReplicas in the callback of the replay method call, and we will clear the failedReplicas in add method when we meet a flush all edit.

They are in different threads, so it is possible that, we have already clear the failedReplicas due to a flush all edit, then in the callback of replay, we add a replica to the failedReplicas because of a failure of replicating, although the failure is actually before the flush all edit.

We should find a way to fix this.
