-----------------------------------
Summary: can flink on k8s use pv using NFS and pvc as the hight
avalibility storagedir
Key: FLINK-20797
URL: https://issues.apache.org/jira/browse/FLINK-20797
Project: Flink
Issue Type: New Feature
Components: Client / Job Submission
Environment: FLINK 1.12.0
Reporter: hayden zhou
I want to deploy Flink on k8s with HA mode, and I don't want to deploy the HDFS
cluster, and I have an NFS so that I am created a PV that use NFS as the
backend storage, and I created a PVC for deployment mount.
this is my FLINK configMap
```
kubernetes.cluster-id: mta-flink
high-availability: org.apache.flink.kubernetes.highavailability.
KubernetesHaServicesFactory
high-availability.storageDir: file:///opt/flink/nfs/ha
```
and this is my jobmanager yaml file:
```
volumeMounts:
- name: flink-config-volume
mountPath: /opt/flink/conf
- name: flink-nfs
mountPath: /opt/flink/nfs
securityContext:
runAsUser: 9999 # refers to user _flink_ from official flink image, change if
necessary
#fsGroup: 9999
volumes:
- name: flink-config-volume
configMap:
name: mta-flink-config
items:
- key: flink-conf.yaml
path: flink-conf.yaml
- key: log4j-console.properties
path: log4j-console.properties
- name: flink-nfs
persistentVolumeClaim:
claimName: mta-flink-nfs-pvc
```
It can be deployed successfully, but if I browser the jobmanager:8081 website,
I get the result below:
```
{"errors": ["Service temporarily unavailable due to an ongoing leader election.
Please refresh."]}
```
is the PVC can be used as `high-availability.storageDir`? if it's can be used,
how can I fix this error?
