Verwenden der `Sequence` Einstellung (in AWS ParallelCluster Version 3.6.0 hinzugefügt):

Die `Sequence` Einstellung wird ab AWS ParallelCluster Version 3.6.0 hinzugefügt. Wenn Sie angeben`Sequence`, können Sie mehrere Skripts für eine benutzerdefinierte Aktion auflisten. AWS ParallelCluster unterstützt weiterhin die Konfiguration einer benutzerdefinierten Aktion mit einem einzigen Skript, ohne dies einzuschließen`Sequence`.

AWS ParallelCluster unterstützt nicht, sowohl ein einzelnes Skript als auch `Sequence` dieselbe benutzerdefinierte Aktion einzubeziehen. Schlägt beispielsweise AWS ParallelCluster fehl, wenn Sie die folgende Konfiguration angeben.
