Amazon EMR HBase on Amazon S3 transitioning to EMR S3A with comparable EMRFS performance

Big Data Blog



This article announces Amazon EMR's transition from EMRFS to EMR S3A as the default file system connector for Amazon S3 access, starting with version 7.10.

  • EMR S3A achieves performance parity with EMRFS while offering better standardization
  • Improved portability, community support, and non-blocking I/O capabilities
  • AWS SDK V2 integration provides better credential management
  • YCSB benchmarks show EMR S3A up to 65% faster than OSS S3A
  • HBase on S3 uses S3 for primary storage, HDFS for WALs and operational files
  • Seamless automatic transition for HBase users in EMR 7.10

The transition delivers enhanced performance, standardization, and portability for HBase on Amazon S3 workloads while maintaining enterprise-grade reliability.
