Re: Convert Standalone zookeeper to A 3 node Quorum
Hi Guys, Just to add one more thing which I forgot to ask earlier is there some kind of rollback concept valid for rolling back to single zookeeper and removing the quorum if the quorum did'nt work ? If so what are the steps please.

Re: Convert Standalone zookeeper to A 3 node Quorum
Indeed I went through this Admin guide for my version 3.5.8 and iam a bit confused with this attribute standaloneEnabled it doesn't seems to present as a part of Pristine/out of the box config but docs says its value is true by default, what does it exactly govern , more specific is this be part of my ensemble zk server config?

Re: Convert Standalone zookeeper to A 3 node Quorum
It really depends on your requirements. You should read the admin docs for insight and examples, start here: https://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_designing That said, I have a project here which I use for config generation/testing.

Re: Convert Standalone zookeeper to A 3 node Quorum
Okay thanks, and could you share what's the standard config for ensemble as example? I mean what all parameters it includes. Also do I need to add standaloneEnabled=false on these 2 new zk servers config file as a part of initial base ensemble config as by default this parameter value is true?

Re: Convert Standalone zookeeper to A 3 node Quorum
Hi Patrick, Thanks for guidance here , based on below I only have presently 1 zk node so if I provision 2 new VM and install same version of zookeeper on them should I start them as standalone zookeepers first and then make changes to there server config file? Also what are the valid zk configs that I would need to add on these 2 new VM's zk server config file?

Re: Convert Standalone zookeeper to A 3 node Quorum
Two ways to do it come to mind, which I've used in the past: 1) most straightforward is to "clone" the repos for the two new members of the ensemble in their respective configs/datadirs. Just make sure to update the configs appropriately. Including the "myid" for each server. Then restart the ensemble and verify. 2) You can't go from 1->3 servers just by adding two new servers to the ensemble as they may form a quorum on the "zero" zxid, rather than the zxid of the existing member. Rather you would need to go from 1->2, with quorum, and then from 2->3 with quorum. This will ensure that the true state of the original quorum is maintained (this is what we implemented for Cloudera Manager to ensure proper functioning when increasing quorum size).

Re: Convert Standalone zookeeper to A 3 node Quorum
Hi tison, When you say stop services you mean existing standalone Zk service right? , if that's the case then yes we can. But what's the process ? Also can it be done without re-start I didn't know , can you share both process/steps?

Re: Convert Standalone zookeeper to A 3 node Quorum
I’m working on initiating zookeeper at startup on my Apache server. Super rough draft but I don’t know if that helps interfacing your servers.

Re: Convert Standalone zookeeper to A 3 node Quorum
Can you stop the services for reconfig, or you need an online reconfig? Best, tison.

Convert Standalone zookeeper to A 3 node Quorum
Hello Guys, Iam new in this space, I wanted to know process/steps to convert a single Zk node in standalone presently to a 3 node ZK quorum . What steps should I perform to add make my standalone Zk node a Quorum of 3 zk nodes? I am using ZK version 3.5.8 presently. Note - I have single Zookeeper(Standalone) and 3 Kafka brokers at this point. Regards, Gaurav
