Implementing Kerberos authentication for Apache Spark jobs on Amazon EMR on EKS to access a Kerberos-enabled Hive Metastore

This article provides a comprehensive guide to implementing Kerberos authentication for Apache Spark jobs on Amazon EMR on EKS to securely access a Kerberos-enabled Hive Metastore.

• Configure Spark jobs on EMR EKS with Kerberos credentials via ConfigMaps and Kubernetes secrets
• Deploy HMS with Kerberos authentication in EKS using service principals and keytabs
• Establish VPC peering between Active Directory and EKS VPCs for KDC connectivity
• Spark driver authenticates with KDC to obtain tickets for HMS service access
• Solution supports hybrid environments running both EMR EC2 and EMR EKS workloads
• Includes step-by-step deployment scripts and configuration examples in GitHub repository
• Recommends KMS envelope encryption for keytabs and TLS for Thrift data channel

This solution enables organizations to migrate to EMR EKS while maintaining existing Kerberos security infrastructure and unified authentication across data platforms.
