I deploy flink1.4 on kubernetes 1.9, the jobmanager container is ok, but the
taskmanager contains failed with error:

I know that the the
jobmanager-deployment.yaml
taskmanager-deployment.yaml
I know in flink docker image, it uses environment
{{JOB_MANAGER_RPC_ADDRESS=flink-jobmanager to resolve jobmanager address.
however in flink task container, it can't resolve the hostname flink-jobmanager.
Can anyone help me to fix it? Should I need to setup a DNS to resolve?}}
