---------------------------------------------

Larry, any reason why not using the KeyStore API directly?

> 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.
