Running Zookeeper in a servlet and not as a standalone process

[Guy Moshkowich <GU...@il.ibm.com>]

I would like to deploy Zookeeper in our product which is running as a web 
application.
I'm considering the option of adding a simple servlet to run Zookeeper by 
calling Zookeeper main during servlet initialization.
This can simplify the installation and life cycle management of Zookeeper 
service.

Are there any known issues with this approach?

Don't servlets get instantiated and destroyed at the whims of the
container, and usually in response to a client request? That doesn't
seem to be a very suitable arrangement for a zookeeper server's
lifecycle management, to me.

It sounds to me like you are trying to repurpose a web container for
cluster management. I think there might be better container solutions
for that purpose, though. Have you considered something like Docker,
Mesos, or YARN?
