Flavio Paiva Junqueira updated ZOOKEEPER-464:
---------------------------------------------
Attachment: zookeeper-464-log.txt
Hi Erwin, I still see several comments preceding new methods that we need to
put in javadoc format. A more serious issue is that LedgerDeleteTest failed for
me. I'm attaching the output log. It essentially crashed because it ran out of
heap space.

> 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.
