Hi team. What should be the value of 
controller.host
in controller config for a k8s deployment? I am deploying Pinot to a new env and leaving this field empty results in a NPE during controller startup:
Copy code
java.lang.NullPointerException: null

r
you can probably use add this to the config
Copy code
pinot.set.instance.id.to.hostname=true
p
Well this is set, but not sure why it’s not picking it up. Literally same configs in all other envs, and they work fine. I am probably making a very stupid mistake somewhere.
Here’s my controller config:
Copy code
apiVersion: v1
data:
  pinot-controller.conf: |-
    controller.helix.cluster.name=myenv
    controller.port=9000
    controller.data.dir=/tmp/controller
    controller.zk.str=apache-pinot-zookeeper-bitnami-headless.pinot.svc.cluster.local:2181
    pinot.set.instance.id.to.hostname=true
    pinot.set.instance.id.to.hostname=true
kind: ConfigMap

Oh, I see it’s repeated. Let me try deleting the duplicate line.
r
did you restart the pod. it should automatically pick up
p
Wow so I deleted that duplicate line and it picked it up.

I’ll recheck this. Not sure why duplicate configs are behaving like this. Might be a bug.
Thanks @Rong R
