Flavio Paiva Junqueira commented on ZOOKEEPER-464:
--------------------------------------------------
Hi Erwin, Sorry about the delay to review it. I think this patch is pretty much
ready to get in. I have just a couple of tiny requests:
# I noticed that the two commands you modified in the documentation
(bookkeeperStated.xml and bookkeeperConfig.xml) are going over the paper margin
for the generated pdfs. Could you please break up the lines?
# In LedgerDeleteTest, you're using "//" for multi-line comments. I believe we
have been using "/**/" instead. This is just to keep it consistent with
comments in other parts of the code.
Otherwise, it looks good. If you fix these two things, then I think we will be
able to get it in shortly after.

> 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.
