Amazon EMR 7.6.0 - Hadoop features
-
The default configuration settings for
yarn.scheduler.increment-allocation-mbandyarn.scheduler.minimum-allocation-mbhave 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.
