NIFI-786 AWS credential refactoring and enhancements
Signed-off-by: Joe Skora <[email protected]>
This closes #244.
> Add other supporting options for configuring credentials for AWS processors
> ---------------------------------------------------------------------------
>
> Key: NIFI-786
> URL: https://issues.apache.org/jira/browse/NIFI-786
> Project: Apache NiFi
> Issue Type: Improvement
> Affects Versions: 0.3.0
> Reporter: Michael Kobit
> Assignee: James Wing
> Priority: Minor
> Fix For: 0.7.0
>
>
> I was looking at https://issues.apache.org/jira/browse/NIFI-770 and looked at
> how the AWS processors credentials are currently configured. As a NFM you
> have a few options with the properties right now:
> 1) set basic, static credentials
> 2) set a credentials properties filepath
> 3) set neither, use anonymous credentials
> I think it would be better if each AWS could rely on a ControllerService that
> returns `AWSCredentialsProvider` (instead of `AWSCredentials`) that gives
> all of the possible implementations that could be used, rather than relying
> on a static credentials. *Provider implementations can be refreshed and can
> also other more complicated implementations, but already have built in
> support for the Static and Properties file that are provided by NiFi today.
> My thinking is that the controller service would be something like
> public interface AwsCredentialsProviderService extends ControllerService {
> AWSCredentialsProvider getCredentialsProvider();
> }
> and you could have `StaticAwsCredentialsProviderService`,
> `PropertiesFileAwsCredentialsProviderService`, and
> `AnonymousAwsCredentialsProviderService` to provide the functionality that is
> supported right now. Additional credential providers could be added later, as
> there a bunch more AWS provided versions that I think could fit in well.
