After comments the config out, it is OK now. would like to work with helm to solve this issue later.

When we comment out the following code in grafana in values.yaml:

#  resources:
#    requests:
#      memory: 4Gi
#      cpu: 1

everything is ok. And in helm2, the issue does not appear to occur

I think the change was for helm3. We might need to consider support both helm3 and helm2.
