Amazon EMR 7.6.0 - Hadoop features

  • The default configuration settings for yarn.scheduler.increment-allocation-mb and yarn.scheduler.minimum-allocation-mb have been modified from 32 to 1, which effectively disables container resource normalization in YARN.

  • The S3A Filesystem in Hadoop has been enhanced to support request-level credential vending. With this feature, every Amazon S3 request made will utilize an AwsCredentialsProvider. This ensures improved flexibility and security by dynamically providing credentials for each request.

  • The S3A Filesystem in Hadoop supports S3 client-side encryption.
