Pods still in initialising state

Hi there,

Deployed dremio helm chart on kubernetes AWS EKS .
Nodes are in ready state.
Dremio-client service has external-ip assigned
no errors

But dremio-master-0 and dremio-executor-0 pods are in init state and in logs could see below:
$kubectl logs dremio-executor-0
Error from server (BadRequest): container “dremio-executor” in pod “dremio-executor-0” is waiting to start: PodInitializing

$ kubectl get pods
dremio-executor-0 0/1 Init:0/2 0 99s
dremio-master-0 0/1 Init:1/4 0 113m
zk-0 0/1 ImagePullBackOff 0 113m
zk-1 0/1 ImagePullBackOff 0 113m

have changed values.yml,core-site.xml and dremio.config files.
Still pods are not in running state.
and unable to access the dremio UI using externalip and port
Could you please help with resolving this
