正是按照本页的逐步说明,我试图将我的一个DynamoDB表的内容导出到S3存储桶.我完全按照指示创建了一个管道,但它无法运行.它似乎无法识别/运行EC2资源来执行导出.当我通过AWS Console访问EMR时,我看到如下条目:

Cluster: df-0..._@EmrClusterForBackup_2015-03-06T00:33:04Terminated with errorsEMR service role arn:aws:iam::...:role/DataPipelineDefaultRole is invalid

为什么我收到此消息？我是否需要为管道设置/配置其他东西？

更新:在IAM->RolesAWS控制台下我看到这个DataPipelineDefaultResourceRole:

{
    "Version": "2012-10-17",
    "Statement": [{
    "Effect": "Allow",
    "Action": [
        "s3:List*",
        "s3:Put*",
        "s3:Get*",
        "s3:DeleteObject",
        "dynamodb:DescribeTable",
        "dynamodb:Scan",
        "dynamodb:Query",
        "dynamodb:GetItem",
        "dynamodb:BatchGetItem",
        "dynamodb:UpdateTable",
        "rds:DescribeDBInstances",
        "rds:DescribeDBSecurityGroups",
        "redshift:DescribeClusters",
        "redshift:DescribeClusterSecurityGroups",
        "cloudwatch:PutMetricData",
        "datapipeline:PollForTask",
        "datapipeline:ReportTaskProgress",
        "datapipeline:SetTaskStatus",
        "datapipeline:PollForTask",
        "datapipeline:ReportTaskRunnerHeartbeat"
    ],
    "Resource": ["*"]
    }]
}

这个用于DataPipelineDefaultRole:

{
    "Version": "2012-10-17",
    "Statement": [{
    "Effect": "Allow",
    "Action": [
        "s3:List*",
        "s3:Put*",
        "s3:Get*",
        "s3:DeleteObject",
        "dynamodb:DescribeTable",
        "dynamodb:Scan",
        "dynamodb:Query",
        "dynamodb:GetItem",
        "dynamodb:BatchGetItem",
        "dynamodb:UpdateTable",
        "ec2:DescribeInstances",
        "ec2:DescribeSecurityGroups",
        "ec2:RunInstances",
        "ec2:CreateTags",
        "ec2:StartInstances", …
