Erwin Tam updated ZOOKEEPER-464:

    Attachment: ZOOKEEPER-464.patch

Uploaded a patch for BK ledger deletes.  Could use more unit tests perhaps.  
Known issues are with using the BufferedChannel currently when reading in the 
ledgers that make up the entry log files.  If the BufferedChannel is created 
for an already existing entry log file we want to read from (but not write to), 
it results in an infinite loop.

> An application using BookKeeper is likely to use a large number of ledgers 
> over time. Such an application might not need all ledgers created over time 
> and might want to delete some of these ledgers to free up some space on 
> bookies. The idea of this jira is to implement a procedure that enables an 
> application to garbage-collect unwanted ledgers.
> To garbage-collect a ledger, we need to delete the ledger metadata on 
> ZooKeeper, and delete the ledger data on corresponding bookies.
