Quote from https://docs.aws.amazon.com/emr/latest/ManagementGuide/UsingEMR_ViewingMetrics.html:

Metrics are updated every five minutes and automatically collected and pushed to CloudWatch for every Amazon EMR cluster. This interval is not configurable. There is no charge for the Amazon EMR metrics reported in CloudWatch. Metrics are archived for two weeks, after which the data is discarded.

This SO answer Sending EMR Logs to CloudWatch implies an installation, but the question is 2 years old now.

So, do we need to install the CloudWatch Agent on EMR? My view is yes. Next week I will be trying it out, but a look ahead would be appreciated.

Added the answer as it is hard to find.
