> Currently the S3 native implementation {{org.apache.hadoop.fs.s3native.Jets3tNativeFileSystemStore}} requires credentials to be set explicitly. Amazon allows setting credentials for instances instead of users, via roles. Such are rotated frequently and kept in a local cache all of which is handled by the AWS SDK in this case the {{AmazonS3Client}}. The SDK follows a specific order to establish whether credentials are set explicitly or via a role:
> - Environment Variables: AWS_ACCESS_KEY_ID and AWS_SECRET_KEY
> - Java System Properties: aws.accessKeyId and aws.secretKey
> - Instance Metadata Service, which provides the credentials associated with the IAM role for the EC2 instance
> as seen in http://docs.aws.amazon.com/IAM/latest/UserGuide/role-usecase-ec2app.html
> To support this feature the current {{NativeFileSystemStore}} implementation needs to be altered to use the AWS SDK instead of the JetS3t S3 libraries.
> A request for this feature has previously been raised as part of the Flume project (FLUME-1691) where the HDFS on top of S3 implementation is used as a manner of logging into S3 via an HDFS Sink.
