`Sequence` 설정은 AWS ParallelCluster 버전 3.6.0부터 추가됩니다. `Sequence`을 지정하는 경우 사용자 지정 작업에 사용할 여러 스크립트를 나열할 수 있습니다. AWS ParallelCluster 는 `Sequence`를 포함하지 않고 단일 스크립트로 사용자 정의 액션을 구성할 수 있도록 계속 지원합니다.

AWS ParallelCluster 는 동일한 사용자 지정 작업에 `Sequence` 대해 단일 스크립트와를 모두 포함하는 것을 지원하지 않습니다. 예를 들어, 다음 구성을 지정하면 AWS ParallelCluster 실패합니다.
