Summary: make last AWS credential provider in default auth chain
EC2ContainerCredentialsProviderWrapper
Key: HADOOP-16470
URL: https://issues.apache.org/jira/browse/HADOOP-16470
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.3.0
Reporter: Steve Loughran
There's a new credential provider in the AWS SDK,
{{com.amazonaws.auth.EC2ContainerCredentialsProviderWrapper}}
this is designed to work within AWS containers as well as EC2 VMs, using env
vars to find container credentials first, falling back to the IAM metadata
service. This way, when deployed in a container or EC2 VM, it will always find
the session credentials for the deployed IAM Role
