Yes, I think whirr will work in my case.

I am actually trying to create around 15 node replicated zookeeper group. And I have to create around 10 such groups.

So from what I understood is I basically have to run the "whirr launch cluster" command 10 times?

Thanks,

That said, it's not clear to me what you mean. "every time a new
instance is spawned zk will run on it". Surely you don't mean a zk
server (the max you might run is say 5 or perhaps 7 servers), however
if it's a client then you'd be including the zk jar with your
application code. Perhaps you could elaborate?

Hi,

I need some suggestion on how to automate zookeeper deployment on EC2
instances. I know how to run zookeeper on a single EC2 instance manually.
But I want to automate such that every time a new instance is spawned,
zookeeper will be run on it. There will be around 200 such instances.

Any pointers will be helpful.

Thanks,
