> Key: LIVY-724

> Remaining Estimate: 0h

> In this JIRA, we want to support recover a session from the state store to
> Livy server memory when the session is used.
> In the current single node recover, when a server restarts, it will recover
> the sessions in the state store in a batch.
> In the multi-active scenario, we propose a new session recovery solution.
> When a server leaves the cluster, its sessions will be transferred to other
> servers. Instead of transferring them in a batch, each Livy session gets
> recovered when a request for it arrives. It will save the session switch time.
