> 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
> Assignee: Duo Zhang
> Priority: Major
> Fix For: HBASE-26233
>
>
> 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.
