In this chapter, we will dive deep into EMR cluster monitoring, scaling, and high-availability aspects. To test out the features and configurations, you will need the following resources before you get started:
- An AWS account
- An IAM user that has permission to create an EMR cluster, EC2 instances, and dependent IAM roles and has access to CloudWatch, CloudTrail logs, and more
Now, let's dive deep into the EMR cluster's monitoring aspects, which includes web interfaces available for your cluster's big data applications and Amazon CloudWatch and CloudTrail logs.
