Steven Wong updated HADOOP-12723:
---------------------------------
Description:
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}} and
added to its credentials provider chain.
The configured credentials provider should implement
{{com.amazonaws.auth.AWSCredentialsProvider}} and have a constructor that
accepts {{(URI name, Configuration conf)}}.
