Rakesh R commented on BOOKKEEPER-733:
-------------------------------------

thanks [~ikelly] for the idea. I'll try a logic considering this point.

> Improve ReplicationWorker to handle the urLedgers which already have same 
> leder replica in hand

>                 Key: BOOKKEEPER-733
>                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-733
>             Project: Bookkeeper
>          Issue Type: Bug
>          Components: bookkeeper-auto-recovery
>    Affects Versions: 4.2.2, 4.3.0
>            Reporter: Rakesh R
>            Assignee: Rakesh R
>
> +Scenario:+
> Step1 : Have three bookies BK1, BK2, BK3
> Step2 : Have written ledgers with quorum 2
> Step3 : Unfortunately BK2 and BK3 both went down for few moments.
> The following logs are flooded in BK1 autorecovery logs. RW is trying to 
> replicate the ledgers, but it simply skip this fragment and moves to next 
> cycle when it sees a replica found in his hand. IMO, we should have a 
> mechanism in place to avoid unnecessary cycles.
