--------------------------------------

I think we just need to respond more actively to the community's request. For 
example this one, and also some other hbase guys requires some kind of 
location-aware distribution schedules.

go back to this jira, there are two jiras related to their requirements: 
BOOKKEEPER-562 and BOOKKEEPER-257. for listing ledgers, it would be handled in 
BOOKKEEPER-257. for this issue, I am not sure what exactly they required. but I 
think both LedgerHandle#isClosed and BookKeeper#isClosed(ledgerId) are useful. 
I could add such call to avoid instantiate a LedgerHandle.

> We need to be able to differentiate between open and closed ledgers, because 
> we want to persist ledgers which are closed and wait for ledgers that are 
> open to close.
> There doesn't seem to be an easy way to get a list of closed / open ledgers 
> or to query bk to ask if a specific ledger is open or closed.
