>                 URL: https://issues.apache.org/jira/browse/HBASE-12797
>             Project: HBase
>          Issue Type: Improvement
>          Components: Replication
>    Affects Versions: 0.99.2
>            Reporter: Jianwei Cui
>            Priority: Minor

> ReplicationSyncUp will check all old sources has been removed every 10 seconds (ReplicationSyncUp.SLEEP_TIME):
> {code}
>       int numberOfOldSource = 1; // default wait once
>       while (numberOfOldSource > 0) {
>         Thread.sleep(SLEEP_TIME);
>         numberOfOldSource = manager.getOldSources().size();
>       }
> {code}
> However, the default "replication.sleep.before.failover" is 30 seconds, which will make NodeFailoverWorker sleep at least 30 seconds before transferring recover queue. Therefore, ReplicationSyncUp will do nothing and return directly with default configuration.
> When using ReplicationSyncUp, the goal tends to be syncing-up the not-replicated data to peer cluster as soon as possible, is it reasonable to set "replication.sleep.before.failover" to 0 in this situation, and also make sure ReplicationQueues.getListOfReplicators().size() = 0 before returned?
