> As HBASE-27230 and HBASE-27223 said, if {{WAL.sync}} throws an exception, we should abort the region server to avoid the data inconsistent between the primary region and secondary region replicas, so we have no need to replicate to secondary region replicas when  {{WAL.sync}} throws an exception.
