aws emr add-steps

Add a list of steps to a cluster


--cluster-id <string>A unique string that identifies a cluster. The create-cluster command returns this identifier. You can use the list-clusters command to get cluster IDs
--steps <list...>Specifies a list of steps to be executed by the cluster. Steps run only on the master node after applications are installed and are used to submit work to a cluster. A step can be specified using the shorthand syntax, by referencing a JSON file or by specifying an inline JSON structure. Args supplied with steps should be a comma-separated list of values (Args=arg1,arg2,arg3) or a bracket-enclosed list of values and key-value pairs (Args=[arg1,arg2=value,arg4)
