Use `S3Tool` to inspect data - **EMR → EC2**: Clusters run on EC2 instances. Use `EC2Tool` to inspect the underlying instances - **EMR → CloudWatch**: Cluster metrics and logs in CloudWatch. Use `CloudWatchLogTool` to read logs - **EMR → IAM**: Clusters use EC2 instance profiles and service roles. Use `IAMTool` to inspect - **EMR → Glue Data Catalog**: EMR can use Glue Data Catalog as Hive metastore.
