# Submitting a job that source is Kafka, and Kafka partition is 1 , if set source Parallelism to 4,the job will be submitted successfully and source operator is RUNNING status but three Parallelism task is FINISHED

We want to be able to trigger checkpoint and store it if we have a finished node in operator,or we want to be able to check Parallelism problem when we submit the job(eg : if Parallelism > kafkaPartition then submit unsuccessfully)
