Description

We have two raft cluster,

A cluster IP is

A1:7082,A2:7082,A3:7082

B cluster master ip is 

B1:7082,B2:7082,B3:7082

 

 

When we start A cluster we use a wrong config 

A1:7082,A2:7082,B3:7082

After we start the cluster we found we use wrong config.

But this info has been write to raft-meta.conf.

Then after we restart A cluster, when client connect to A cluster.

It connect to A cluster follower then return the cached leader address, the leader peer id is 3, but in the meta conf, the peer rpc link is B3:7082.

Then cause it connect to cluster B.

 

Its caused by RaftPeer object equal only compare peerId cause it won't refresh raft-meta.conf
