Benoy Antony commented on MAPREDUCE-4550:
-----------------------------------------
I was following the pattern of Compressor/DeCompressor interfaces. But that is
more like an implementation detail. So I'll try to combine them and see if it
holds good.

> 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.
