com.orbitz.consul.ConsulException: Consul cluster has no elected leader #457

Hi Everyone,

We have very huge consul cluster and some project needs consul-client-1.3.3 for cbes integration.

But we are getting error as below.

11:31:45.530 [OkHttp http://consul-api.external:8500/...] ERROR c.o.c.c.ConsulCache - Error getting response from consul for health.service "XXX_pod_name_XXX", will retry in 10000 MILLISECONDS

I'm sure there is no problem with the consul cluster because the other 4000 clients are working fine. (In particular, there is no such thing as the absence of a leader.) Due to some problems we are not using a version greater than 1.3.3.

Do you have an opinion on this station ?

Best Regards

Hi, I also get 'Consul cluster has no elected leader', despite both UI and statusClient.getLeader() stating that there is a leader. Turning off streaming fixed my issue. I suspect this is connected to https://github.com/rickfast/consul-client/pull/456 , but i dont have super-solid evidence

there is "use_streaming_backend" key in consul node configuration to control that
