Flavio Junqueira commented on BOOKKEEPER-355:
---------------------------------------------

It looks like this assertion in LedgerMetadata is failing: assert 
ensembles.isEmpty() || startEntryId >= ensembles.lastKey();
                
> Ledger recovery will mark ledger as closed with -1, in case of slow bookie is 
> added to ensemble during  recovery add

> Scenario:
> ------------
> 1. Ledger is created with ensemble and quorum size as 2, written with one 
> entry
> 2. Now first bookie is in the ensemble is made down.
> 3. Another client fence and trying to recover the same ledger
> 4. During this time ensemble change will happen and new bookie will be added. 
> But this bookie is not able to connect.
> 5. This recovery will fail.
> 7. Now previously added bookie came up.
> 8. Another client trying to recover the same ledger.
> 9. Since new bookie is first in the ensemble, doRecoveryRead() is reading 
> from that bookie and getting NoSuchLedgerException and closing the ledger 
> with -1
> i.e. Marking the ledger as empty, even though first client had successfully 
> written one entry.
