The Problem
The problem is obvious, the client-go package (version v2.0.0-alpha.0.0.20190115164855-701b91367003) used by tidb-operator is too old.
From Kubernetes v1.16.2 , you can not find deployment and statefulset in apps/v1beta or extensions/v1beta any more and they are now can only be found in apps/v1. The client-go version should be upgraded or just try to use apps/v1 instead of apps/v1beta and extensions/v1beta.
