------------------------------------------
Would you mind to point out the code where handoff happens?
> Improve Leader Change Mechanism
> -------------------------------
>
> Key: ZOOKEEPER-2076
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2076
> Project: ZooKeeper
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.5.0
> Reporter: Alexander Shraer
>
> When a leader is removed during a reconfiguration, ZOOKEEPER-107 uses a
> mechanism where the old leader nominates the new one. Although it reduces the
> time for a new leader to be elected, it still takes too long. This JIRA is
> for two things:
> 1. Improve the mechanism, e.g., avoid loading snapshots, etc. during the
> handoff.
> 2. Make it a first-class citizen & export it as a client API. We get
> questions about this once in a while - how do I cause a different leader to
> be elected ? Currently the response is either kill or reconfigure the current
> leader.
> Any one interested to work on this ?
