             Summary: Create an API to separate Credentials/Password Storage from Applications
                 Key: HADOOP-10607
                 URL: https://issues.apache.org/jira/browse/HADOOP-10607
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
            Reporter: Larry McCay
            Assignee: Owen O'Malley
             Fix For: 3.0.0


As with the filesystem API, we need to provide a generic mechanism to support multiple key storage mechanisms that are potentially from third parties. 

An additional requirement for long term data lakes is to keep multiple versions of each key so that keys can be rolled periodically without requiring the entire data set to be re-written. Rolling keys provides containment in the event of keys being leaked.

Toward that end, I propose an API that is configured using a list of URLs of KeyProviders. 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.
