Alejandro Abdelnur commented on HADOOP-10607:
---------------------------------------------
Steve, Larry, Owen,
I'm not disputing the usefulness of the {{CredentialsProvider}} at all. I also
have concrete usecases outside of Hadoop.
Still, my concern is that Hadoop is being use a dumping ground of random stuff
for the convenience of other projects. Hadoop should only ship code that Hadoop
itself uses.
I understand the convenience, for all downstream projects, to have this API in
Hadoop itself: It is available for free.
IMO, the {{CredentialProvider}} should not be shipped in a Hadoop release until
Hadoop makes use of it. It can leave in trunk until then.
I don't have anything to add, I've explained clearly my position, now it is
your call to decide if the {{CredentialProvider}} should be shipped with Hadoop
at the moment or not.

> As with the filesystem API, we need to provide a generic mechanism to support
> multiple credential storage mechanisms that are potentially from third
> parties.
> We need the ability to eliminate the storage of passwords and secrets in
> clear text within configuration files or within code.
> Toward that end, I propose an API that is configured using a list of URLs of
> CredentialProviders. The implementation will look for implementations using
> the ServiceLoader interface and thus support third party libraries.
> Two providers will be included in this patch. One using the credentials cache
> in MapReduce jobs and the other using Java KeyStores from either HDFS or
> local file system.
> A CredShell CLI will also be included in this patch which provides the
> ability to manage the credentials within the stores.
