Arun Suresh commented on MAPREDUCE-5890:
----------------------------------------
The -1 on the release audit is expected and caused due to the
{{CHANGES-fs-encryption.txt}} file having no license header.. This file is not
related to this patch.. And should go away once merged..
Output of patchReleaseAuditProblems.txt :
{noformat}
!?????
/home/asuresh/hadoop-common/hadoop-hdfs-project/hadoop-hdfs/CHANGES-fs-encryption.txt
Lines that start with ????? in the release audit report indicate files that do
not have an Apache license header.

> 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.
