Alejandro Abdelnur commented on MAPREDUCE-5890:
-----------------------------------------------
LGTM.
One minor nit (i can take care of it when committing), in
{{JObSubmitter.java#copyAndConfigureFiles()}} javadoc, line 295 no needed
change.
[~chris.douglas], I believe all our suggestions/concerns have been addressed.
Do you want to do a new pass on the patch?
I'll wait a few days to commit.

> 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.
