AWS emr medium security documentation change

Service: emr · 2025-06-25 · Security-related medium

Summary

Corrected configuration key for custom AWS credentials provider in Spark job example

Security assessment

The incorrect key 'spark.hadoop.fs.s3.customAWSCredentialsProvider' could lead to misconfiguration, potentially causing jobs to use default credentials instead of the intended AssumeRole provider. This fixes a security-related configuration error.
