+ 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.
