> we can solve it by following :
> 1) increase the session timeout(but i think it is not a good idea. because we 
> do not know how long to set is suitable)
> 2) close the hbase replication. It is not a good idea too, when our user uses 
> this feature
> 3) we need add retry times, for example when it has already happened three 
> times, we set the ReplicationLogCleaner and SnapShotCleaner stop
> that is all my ideas, i do not konw it is suitable, If it is suitable, could 
> i commit a PR?
> Does anynode have a good idea.
