> 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.
