panic: assertion failed: leader.elected.at.same.term.283

dessalines opened this issue 10 years ago · 2 comments

Answer 2 · 2015-04-23T23:39:33.000Z

FYI, go-raft is no longer maintained. #244

If you need a raft implementation I would suggest the etcd/raft library: https://godoc.org/github.com/coreos/etcd/raft

There are other libraries too, I just don't have the links handy.
