If unchecked which is default, plugin will try to resubmit job if it was failed due to EC2 Spot instance interruption. If checked auto resubmit will be disabled.

Interrupted job will be shown as failed or aborted see pipeline notes below. While copy will be submitted into jenkins queue to execute or any possible node.

Parametrized job will be resubmitted with same parameters as defined for interrupted.

In case if job is pipeline (workflow) interrupted task will be aborted as workflow usually don't fail in case of node interruption and wait until node will be online. Plugin force job to abort and resubmit.
