-------------------------------------
Summary: Configurable finalizeWait for FastLeaderElection
Key: ZOOKEEPER-1516
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1516
Project: ZooKeeper
Issue Type: Improvement
Components: leaderElection, quorum, server
Affects Versions: 3.3.5
Environment: Gentoo linux, any environment is affected.
Reporter: Ian Babrou
FastLeaderElection has final static int finalizeWait = 200. This is time to
wait after successful leader election. I don't know what could happen, but
200ms is too slow for production environment under heavy load.
I changed it to 20ms and everything still works for me.
I propose to make this value configurable with default value of 200 to not
affect current installations.
Combined with #ZOOKEEPER-1515 it could improve leader election and make it 10x
times faster: 1500ms -> 180ms including 100ms for 2 faileed new leader
connections.
