>             Project: Livy
>          Issue Type: Epic

> In this JIRA we want to discuss how to implement multi-active high 
> availability in Livy.
> Currently, Livy only supports single node recovery. This is not sufficient in 
> some production environments. In our scenario, the Livy server serves many 
> notebook and JDBC services. We want to make Livy service more fault-tolerant 
> and scalable.
> There're already some proposals in the community for high availability. But 
> they're not so complete or just for active-standby high availability. So we 
> propose a multi-active high availability design to achieve the following 
> goals:
> # One or more servers will serve the client requests at the same time.
> # Sessions are allocated among different servers.
> # When one node crashes, the affected sessions will be moved to other active 
> services.
> Here's our design document, please review and comment:
