Summary

Hadoop 3.3.4's default S3A credential chain does not include
WebIdentityTokenCredentialsProvider, which is required for IRSA (IAM Roles for Service Accounts) on EKS. When Flink runs Iceberg jobs with Hadoop catalog on S3, the S3A filesystem fails to authenticate.See DataSQRL/sqrl#1850 for full root cause analysis and manual testing evidence.
