-------------------------------------------
Summary: 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 ?
