> And I'm a bit interest on how do you guys manage datanode or namenode on K8s? They have local storage, so if you delete the pod and launch a new one at other places, the data will be lost We currently don't run DataNodes in k8s. For namenodes we use StatefulSet with EBS backed. For DataNodes we don't want to use EBS, too expensive. When we eventually get to then we plan to use FlexVolumes to basically provision space on particular SSD-backed kube nodes. So if pod restarts, it would go to the same node if it's available. If not, it would go elsewhere and lose its data but this is how things work outside k8s and is handled by hdfs replication. Sadly can't give more details than this right now because it's been on hold for a while so we can work on other things. -- This is an automated message from the Apache Git Service.
