I ran this command using the example from the CLI page on the Flink website:
$ ./bin/flink run-application \ —target kubernetes-application \
—parallelism 8 \ -Dkubernetes.cluster-id= \
-Dtaskmanager.memory.process.size=4096m \ -Dkubernetes.taskmanager.cpu=2 \
-Dtaskmanager.numberOfTaskSlots=4 \ -Dkubernetes.container.image= \
—pyModule word_count \ —pyFiles
/opt/flink/examples/python/table/batch/word_count.py
How do I shut the cluster down?
Also I’m getting this error when running ./bin/flink list
org.apache.flink.util.FlinkException: Failed to retrieve job list.
