You can't modify hbase-site.xml nor hbase-env.sh in the pod. This files are mounted from the hbase configmap.
If you want to modify them, you have to edit the corresponding configmap and restart the pod (or just delete the pod and wait for de statefulset to deploy a new one):

kubectl edit configmap RELEASE_NAME-hbase

Hi @cgiraldo , Thanks for responding,
I am not trying to modify above files in POD , but these exceptions are coming while deploying chart as is , without doing any changes. I am thinking its something which is because of user permissions.
These exceptions are throwing from hbase-configmap.yaml while executing below code. Also at the time of starting master to create log file.

for f in hbase-site.xml hbase-env.sh; do
  if [[ -e ${CONFIG_DIR}/$f ]]; then
    cp ${CONFIG_DIR}/$f $HBASE_PREFIX/conf/$f
  else
    echo "ERROR: Could not find $f in $CONFIG_DIR"
    exit 1
  fi
done

Any suggestions to add user specific info to run config map ?
