Steve Loughran commented on HADOOP-12723:
-----------------------------------------
PS, I'm being strict about S3 Patches: you do have to declare that you've run
all the aws tests against an S3 Implementation, and state which AWS location
you worked with; if some in-house thing, declare that + also run against AWS.
This is our due diligence filter; it takes long enough for those test to
complete that it kills the review process for the reviewer to do all the work.

> S3A: Add ability to plug in any AWSCredentialsProvider
> ------------------------------------------------------
>
> Key: HADOOP-12723
> URL: https://issues.apache.org/jira/browse/HADOOP-12723
> Project: Hadoop Common
> Issue Type: New Feature
> Components: fs/s3
> Affects Versions: 2.7.1
> Reporter: Steven Wong
> Assignee: Steven Wong
> Attachments: HADOOP-12723.0.patch, HADOOP-12723.1.patch,
> HADOOP-12723.2.patch, HADOOP-12723.3.patch, HADOOP-12723.4.patch

> Although S3A currently has built-in support for
> {{org.apache.hadoop.fs.s3a.BasicAWSCredentialsProvider}},
> {{com.amazonaws.auth.InstanceProfileCredentialsProvider}}, and
> {{org.apache.hadoop.fs.s3a.AnonymousAWSCredentialsProvider}}, it does not
> support any other credentials provider that implements the
> {{com.amazonaws.auth.AWSCredentialsProvider}} interface. Supporting the
> ability to plug in any {{com.amazonaws.auth.AWSCredentialsProvider}} instance
> will expand the options for S3 credentials, such as:
> * temporary credentials from STS, e.g. via
> {{com.amazonaws.auth.STSSessionCredentialsProvider}}
> * IAM role-based credentials, e.g. via
> {{com.amazonaws.auth.STSAssumeRoleSessionCredentialsProvider}}
> * a custom credentials provider that satisfies one's own needs, e.g.
> bucket-specific credentials, user-specific credentials, etc.
> To support this, we can add a configuration for the fully qualified class
> name of a credentials provider, to be loaded by
> {{S3AFileSystem.initialize(URI, Configuration)}}.
> The configured credentials provider should implement
> {{com.amazonaws.auth.AWSCredentialsProvider}} and have a constructor that
> accepts {{(URI uri, Configuration conf)}}.
