Flavio Junqueira commented on BOOKKEEPER-773:
---------------------------------------------
I'm curious to know how often one needs to execute such a command. This is a
rare command to use, yes? I also don't like such long names for commands, what
about "bkrename" or "renamebookie"?
The order of execution in the patch:
{noformat}
+ // creates new cookie and write to zookeeper
+ Cookie newCookie = cookie.copy();
+ newCookie.writeToZooKeeper(zk, newConf);
+
+ LOG.info("Updating cookie file present in journalDirectory
{}", journalDirectory);
+ LOG.info("Updating cookie file present in ledgerDirectories
{}", ledgerDirectories);
+ newCookie.writeToDirectory(journalDirectory);
+ for (File dir : ledgerDirectories) {
+ newCookie.writeToDirectory(dir);
+ }
+ cookie.deleteFromZooKeeper(zk, conf);
{noformat}
seems to swap 3 and 4 in this sequence:
{noformat}
3. update new cookie into local directories.
4. create new cookie with new zk path with new bookie id
5. delete the old one.
{noformat}
> Provide admin tool to rename bookie identifier in Cookies
