Hi John,
Seems Ivan already worked on upgradation framework. I am not sure about the filesystem layout changes with previous version as i was not aware of older versions code changes. Pls Refer * BOOKKEEPER-172<https://issues.apache.org/jira/browse/BOOKKEEPER-172> You can find some details here: http://zookeeper.apache.org/bookkeeper/docs/trunk/bookkeeperConfig.html Hope this will help you. Regards, Uma ________________________________ From: John Nagro [[email protected]] Sent: Thursday, May 03, 2012 7:09 PM To: [email protected] Subject: rolling restarts hello - I have a cluster with 5 bk nodes, my client settings are to use 3 at a time with a quorum of 2. I want to upgrade the software of a live cluster from an older 4.1-SNAPSHOT to a newer one. I am under the impression that I should not need to upgrade the filesystem since I've already done that when moving to 4.1. Am I correct in that I should be able to bring down the nodes one at a time, replace the jar, and bring them back up. As long as I do it one at a time the cluster should continue to operate properly? also - there doesn't appear to be any sort of graceful shutdown code, and the docs show ^C in a few places - so thats how i've been bringing nodes down. that is still the standard procedure? thanks! -John Nagro
