Hi all We want to assign storageClass to pinot zookeeper in

Question

Hi all We want to assign storageClass to pinot zookeeper in the helm chart so that whenever a pinot zookeeper pod gets created it automatically claims a PV But I see there is no direct way to assign using values yaml We tried installing incubator zookeeper using the below command ```helm n my pinot kube install pinot zookeeper incubator zookeeper set replicaCount=1``` and disabled the zookeeper in helm pinot values yaml by modifying zookeeper enabled to false But we see face an error from ` helpers tpl` indicating not able to fetch the `zookeeper url` and related to `configurationOverride` ```Error template pinot templates server statefulset yml 63 27 executing pinot templates server statefulset yml at lt include zookeeper url gt error calling include template pinot templates helpers tpl 79 33 executing zookeeper url at lt index Values configurationOverrides zookeeper connect gt error calling index index of nil pointer``` Any help is appreciated

You can find it under zookeeper helmChart stuck out tongue in short here are the options under `zookeeper` section in `values yaml` file ```persistence enabled true zookeeper data Persistent Volume Storage Class If defined storageClassName lt storageClass gt If set to storageClassName which disables dynamic provisioning If undefined the default or set to null no storageClassName spec is set choosing the default provisioner gp2 on AWS standard on GKE AWS amp OpenStack storageClass accessMode ReadWriteOnce size 5Gi```

if you already have zk then disable zk should be good I will check the ` helpers tpl` script

Xiang Fu · Answer

can you try to define `zookeeper url` in the `values yml` file and that should provide the overrided zk url

Thank you < Xiang Fu> for the help I tried mentioning just the below values in values yaml for zookeeper section ```zookeeper enabled false url lt ip gt port lt pod exposed port gt ``` When I install pinot using `helm n my pinot kube install pinot ` it throws error ```Error template pinot templates server statefulset yml 63 27 executing pinot templates server statefulset yml at lt include zookeeper url gt error calling include template pinot templates helpers tpl 79 33 executing zookeeper url at lt index Values configurationOverrides zookeeper connect gt error calling index index of nil pointer``` Line 79 in helpers tpl is ``` $zookeeperConnectOverride = index Values configurationOverrides zookeeper connect ```

I tried ```zookeeper enabled false url lt ip gt port lt pod exposed port gt connect 192 168 49 2 30760 zookeeper connect 192 168 49 2 30760``` Still ```Error template pinot templates server statefulset yml 63 27 executing pinot templates server statefulset yml at lt include zookeeper url gt error calling include template pinot templates helpers tpl 79 33 executing zookeeper url at lt index Values configurationOverrides zookeeper connect gt error calling index index of nil pointer``` Does it have issue with index Values configurationOverrides
