> 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.
