             Summary: Read Proxy Password from Credential Providers in S3 
FileSystem
                 Key: HADOOP-12804
                 URL: https://issues.apache.org/jira/browse/HADOOP-12804
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/s3
            Reporter: Larry McCay
            Assignee: Larry McCay


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.
