Post deployment, if hdfs-datanode pod crashes.
A workaround steps on a TKG cluster::
- Identify the hdfs datanode pod with the issue:
kubectl get pods | grep hdfs
- Delete the corresponding pvc:
kubectl get pvc | grep hdfs kubectl delete pvc <pvc_id> --wait=false
- Delete the corresponding pv:
kubectl get pv | grep hdfs kubectl delete pv <pv_id> --wait=false
- Delete the failing pod:
kubectl delete pod <pod_id>
Note: The pv and pvc are recreated, when the pod is recreated.
