Resolution: Fixed
> Spark on Kubernetes Pod Watcher dumps raw container status
> ----------------------------------------------------------
>
> Key: SPARK-25222
> URL: https://issues.apache.org/jira/browse/SPARK-25222
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: 2.3.0, 2.3.1
> Reporter: Rob Vesse
> Priority: Minor
>
> Spark on Kubernetes provides logging of the pod/container status as a monitor of the job progress. However the logger just dumps the raw container status object leading to fairly unreadable output like so:
> {noformat}
> 18/08/24 09:03:27 INFO LoggingPodStatusWatcherImpl: State changed, new state:
> pod name: spark-groupby-1535101393784-driver
> namespace: default
> labels: spark-app-selector -> spark-47f7248122b9444b8d5fd3701028a1e8, spark-role -> driver
> pod uid: 88de6467-a77c-11e8-b9da-a4bf0128b75b
> creation time: 2018-08-24T09:03:14Z
> service account name: spark
> volumes: spark-local-dir-1, spark-conf-volume, spark-token-kjxkv
> node name: tab-cmp4
> start time: 2018-08-24T09:03:14Z
> container images: rvesse/spark:latest
> phase: Running
> status: [ContainerStatus(containerID=docker://23ae58571f59505e837dca40455d0347fb90e9b88e2a2b145a38e2919fceb447, image=rvesse/spark:latest, imageID=docker-pullable://rvesse/spark@sha256:92abf0b718743d0f5a26068fc94ec42233db0493c55a8570dc8c851c62a4bc0a, lastState=ContainerState(running=null, terminated=null, waiting=null, additionalProperties={}), name=spark-kubernetes-driver, ready=true, restartCount=0, state=ContainerState(running=ContainerStateRunning(startedAt=Time(time=2018-08-24T09:03:26Z, additionalProperties={}), additionalProperties={}), terminated=null, waiting=null, additionalProperties={}), additionalProperties={})]
> {noformat}
> The {{LoggingPodStatusWatcher}} actually already includes code to nicely format this information but only invokes it at the end of the job:
> {noformat}
> 18/08/24 09:04:07 INFO LoggingPodStatusWatcherImpl: Container final statuses:
> Container name: spark-kubernetes-driver
> Container image: rvesse/spark:latest
> Container state: Terminated
> Exit code: 0
> {noformat}
> It would be nice if we continually used the nice formatting throughout the logging.
> We already have patched this on our internal fork and will upstream a fix shortly.
