Use the create-cluster subcommand to create a transient cluster that terminates when the Flink job completes:

aws emr create-cluster --release-label emr-5.2.1 \
--name "Flink_Transient" \
--applications Name=Flink \
--configurations file://./configurations.json \
--region us-east-1 \
--log-uri s3://myLogUri \
--auto-terminate
--instance-type m5.xlarge \
--instance-count 2 \
--service-role EMR_DefaultRole_V2 \ 
--ec2-attributes KeyName=<YourKeyName>,InstanceProfile=EMR_EC2_DefaultRole \
--steps Type=CUSTOM_JAR,Jar=command-runner.jar,Name=Flink_Long_Running_Session,\
Args="bash","-c","\"flink run -m yarn-cluster /usr/lib/flink/examples/streaming/WordCount.jar
--input s3://amzn-s3-demo-bucket/pg11.txt --output s3://amzn-s3-demo-bucket/alice/""
