             Summary: Key Protection : Define Encryption and Key Protection interfaces and default implementations
                 Key: MAPREDUCE-4550
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4550
             Project: Hadoop Map/Reduce
          Issue Type: Sub-task
          Components: security
            Reporter: Benoy Antony
            Assignee: Benoy Antony


A secret key is read from a Key Store and then encrypted during transport between JobClient and Task. The tasktrackers/nodemanagers decrypt the secrets and provide the secrets to child tasks which part of the job.

This jira defines the interfaces to accomplish the above :

1) KeyProvider - to read keys from a KeyStore

2) Encrypter and Decrypter - to and encrypt and decrypt secrets/data.

The default/dummy implementations will also be added. This includes a KeyProvider implementation to read keys from a Java KeyStore.
