Alejandro Abdelnur commented on MAPREDUCE-5890:
-----------------------------------------------

LGTM. [~asuresh], can you run test-patch locally on the patch and paste the result in the
JIRA? After that, I think we are good to go.

> 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.
