I'm testing Autoscaler through Kubernetes Operator and I'm facing the following issue.
As you know, when a job is scaled down through the autoscaler, the job manager and task manager go down and then back up again.
When this happens, an index out of bounds exception is thrown and the state is not restored from a checkpoint.
gyfora told me via the Flink Slack troubleshooting channel that this is likely an issue with Unaligned Checkpoint and not an issue with the autoscaler, but I'm opening a ticket with Gyula for more clarification.
Please see the attached JM and TM error logs.
