 * <p> Creates a new EMR cluster based on the given request if the cluster with the given name does not already exist. If the cluster already exist, returns

 * EMR cluster definition.</li> <li>A valid cluster name to create.</li> </ul> <p> The request may optionally contain: </p> <ul> <li>A "dry run" flag, which
 * when set to {@code true}, no calls to AWS will occur, but validations and override will. Defaults to {@code false}.</li> <li>An override parameter, which
 * when set, overrides the given parameters in the cluster definition before creating the cluster. Defaults to no override. </li> </ul> <p> A successful
 * response will contain: </p> <ul> <li>The ID of the cluster that was created, or if the cluster already exists, the ID of the cluster that exists. This
 * field will be {@code null} when dry run flag is {@code true}.</li> <li>The status of the cluster that was created or already exists. The status will
 * normally be "Starting" on successful creations. This field will be {@code null} when dry run flag is {@code true}</li> <li>The namespace, definition
 * name, and cluster name of the cluster.</li> <li>The dry run flag, if given in the request.</li> <li>An indicator whether the cluster was created or not.
 * If the cluster already exists, the cluster will not be created and this flag will be set to {@code false}.</li> <li>The definition which was used to
 * create the cluster. If any overrides were given, this definition's values will be the values after the override. This field will be {@code null} if the
 * cluster was not created.</li> </ul> <p> Notes: </p> <ul> <li>At any point of the execution, if there are validation errors, the method will immediately
 * throw an exception.</li> <li>Even if the validations pass, AWS may still reject the request, which will cause this method to throw an exception.</li>
