为什么亚马逊网络服务CloudFormation抛出“遇到不支持的属性InstanceGroups"？

Question

当我部署下面的AWS CloudFormation脚本时，我得到了以下错误：“遇到不支持的属性InstanceGroups”

我过去使用过InstanceGroups，没有任何问题。下面是其他人如何使用它的示例：https://noise.getoto.net/tag/amazon-emr/

我使用的是EMR 5.17.0，这是我以前设置过的。

加载CF脚本时，应创建一个AWS EMR集群

亚马逊网络服务建议您在Instances下设置MasterInstanceGroup和CoreInstanceGroup

我给您提供一个EMR Cluster with Hadoop, Hbase, Spark, Ganglia and Zookeeper的Instances属性的示例

      Instances:
        Ec2KeyName: !Ref KeyName
        Ec2SubnetId: !ImportValue MySubnetPrivateA
        EmrManagedMasterSecurityGroup: !ImportValue EmrMasterSgId
        AdditionalMasterSecurityGroups:
          - !ImportValue EmrMasterAdditionalSgId
        EmrManagedSlaveSecurityGroup: !ImportValue EmrSlaveSgId
        AdditionalSlaveSecurityGroups:
          - !ImportValue EmrSlaveAdditionalSgId
        ServiceAccessSecurityGroup: !ImportValue EmrServiceSgId
        MasterInstanceGroup:
          InstanceCount: 1
          InstanceType: !Ref MasterInstanceType
          Market: ON_DEMAND
          Name: Master
        CoreInstanceGroup:
          InstanceCount: !Ref NumberOfCoreInstances
          InstanceType: !Ref CoreInstanceType
          Market: ON_DEMAND
          Name: Core
        TerminationProtected: false
      VisibleToAllUsers: true
      JobFlowRole: !Ref EMRClusterinstanceProfile
      ReleaseLabel: !Ref ReleaseLabel
      LogUri: !Ref LogUri
      Name: !Ref EMRClusterName
      AutoScalingRole: EMR_AutoScaling_DefaultRole
      ServiceRole: !Ref EMRClusterServiceRole
      Tags:
        -
          Key: "cluster_name"
          Value: "master.emr.my.com"
