How does leader/follower invoke setupRequestProcessors()?

[朱君 <yf...@360buy.com>]

HI,

I am reading the source code of ZooKeeper 3.3.0, and stucked. 

After the instance of LeaderZooKeeperServer (inherit from QuorumZooKeeperServer which inherits from ZooKeeperServer ) has been created (in class QuorumPeer:657), where does it invoke setupRequestProcessors()? In standalone mode, it is easy to find whre setupRequestProcessors is called. But in quorum mode, i don't know how the function is invoked.

Thanks very much!

You can follow the code to see that the startup() method (in
ZooKeeperServer()) is the one that leads to all the setup methods
being called. Take a look at ServerCnxnFactory.start() and you should
be able to follow how its being called.

OTOH, the start up code isnt very clean right now. It needs a little
bit of cleanup to make it more understandable.

hope that helps
