Kubernetes elastic cluster DNS Caching Issue


Hi ,

We are trying to form the elastic cluster with three nodes using kubernetes .elasticsearch is running on individual pods.

They are not forming the cluster.We have observed that pods can communicate each other by IP Address but not by hostnames. We have created headless service for pods commnication.As it will use statefulsets host names they are not communicating.Please help us in fixing this.We have observed some dns caching is the cause for this.But not sure what is the procedure to fix that.
