如何启动6个核心节点emr集群，每个家庭有2个节点。

 [
  {
    "Name": "MasterFleet",
    "InstanceFleetType": "MASTER",
    "TargetOnDemandCapacity": 1,
    "InstanceTypeConfigs": [{"InstanceType": "m4.xlarge"}]
  },
  {
    "Name": "CoreFleet",
    "InstanceFleetType": "CORE",
    "TargetSpotCapacity": 6,
    "LaunchSpecifications": {
     "SpotSpecification": {
        "TimeoutDurationMinutes": 10,
        "TimeoutAction": "SWITCH_TO_ON_DEMAND"
      }
    },
    "InstanceTypeConfigs": [
      {
        "InstanceType": "m4.large",
        "BidPrice": "0.1"
      },
      {
        "InstanceType": "m4.xlarge",
        "BidPrice": "0.2"
      },
      {
        "InstanceType": "m4.2xlarge",
        "BidPrice": "0.4"
      }
    ]
  }
]

我在aws cli create cluster脚本中传递了config.json文件。

aws emr create-cluster \
  --instance-fleets file://config.json

它根据默认分配策略“lowestPrice”分配来自同一系列的所有实例，如何通过属性“多样化”使其从不同的系列启动实例？

除了大写之外，这看起来是正确的：＆＃34; Masterfleet＆＃34;和＆＃34; Corefleet＆＃34; - 不是＆＃34; MasterFleet＆＃34;和＆＃34; CoreFleet＆＃34;。可能想检查其他人。
