Amazon EMR HBase on Amazon S3 transitioning to EMR S3A with comparable EMRFS performance
Starting with version 7.10, Amazon EMR is transitioning from EMR File System (EMRFS) to EMR S3A as the default file system connector for Amazon S3 access. This transition brings HBase on Amazon S3 to a new level, offering performance parity with EMRFS while delivering substantial improvements, including better standardization, improved portability, stronger community support, improved performance through non-blocking I/O, asynchronous clients, and better credential management with AWS SDK V2 integration. In this post, we discuss this transition and its benefits.
