> HADOOP-12548 added credential provider support for the AWS credentials to 
> S3FileSystem. This JIRA is for considering the use of the credential 
> providers for the proxy password as well.
> Instead of adding the proxy password to the config file directly and in clear 
> text, we could provision it in addition to the AWS credentials into a 
> credential provider and keep it out of clear text.
> In terms of usage, it could be added to the same credential store as the AWS 
> credentials or potentially to a more universally available path - since it is 
> the same for everyone. This would however require multiple providers to be 
> configured in the provider.path property and more open file permissions on 
> the store itself.
