-----------------------------------

    Attachment: MAPREDUCE-5890.13.patch

Uploaded updated patch.. Thanks [~chris.douglas] for all the feedback !!
I've maked the class {{Private}} and {{Unstable}} but can't make the class itself package protected since it exposes public static methods used in a number of places..

> For some sensitive data, encryption while in flight (network) is not sufficient, it is required that while at rest it should be encrypted. HADOOP-10150 & HDFS-6134 bring encryption at rest for data in filesystem using Hadoop FileSystem API. MapReduce intermediate data and spills should also be encrypted while at rest.
