What are the steps for moving a zookeeper server?

[#1]

Many nodes and updates ago, when we first got started with Hadoop, we assigned one of our data nodes as a zookeeper server.

I would like to move that to an edge node.

Is there a document that outlines that steps to accomplish this? I'm on 2.2.8

Similarly, we need to move our ambari metrics server.

Thanks!

@Zack Riesland: I feel there is not a stright forward way to move zookeeper through ambari like any other service. But below link may help you to do it manually. I have not tested it but it may help you.

Here are the steps for metrics http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.0.0/bk_ambari_reference_guide/content/ch_moving_...

For zookeeper go to the individual host page, in host actions select move zk

Thanks, @Artem Ervits.

Do we need to stop any services, etc?

honestly I don't remember but I have done it before. It should walk you through the steps as you click on the menu options. I believe it will stop but obviously try it out in dev cluster. It may take some services down itself. @Zack Riesland

Actually, that isn't an option.

Under "Host Actions", my options are:

start all components

stop all components

restart all components

turn on main. mode

delete host

set rack

download client configs

@Zack Riesland is there a drop down next to the zookeeper service? If it isn't there, it must've been removed. I'll check on a cluster and report back in a bit.

I figured it out. Had to go to services->zookeeper and follow the menus.

Any idea how to move the ambari metrics collector? I don't see any similar options.
