Flavio Junqueira commented on BOOKKEEPER-162:
---------------------------------------------
Correct, we currently don't have an api to check if a ledger is closed. We
assume that it is communicated from a writer to a reader by an external
channel, e.g., through zookeeper. It wouldn't be difficult to have such a call,
though. It is simply checking the ledger metadata on zookeeper.
> LedgerHandle.readLastConfirmed does not work
