Alejandro Abdelnur updated MAPREDUCE-4417:
------------------------------------------
Attachment: MAPREDUCE-4417.patch
Same as last patch, just adding a comment about the performance impact (per
Devaraj's suggestion):
*Using encrypted shuffle will incurs in a significant performance impact. Users
should profile this and potentially reserve 1 or more cores for encrypted
shuffle.*
> add support for encrypted shuffle

> Currently Shuffle fetches go on the clear. While Kerberos provides
> comprehensive authentication for the cluster, it does not provide
> confidentiality.
> When processing sensitive data confidentiality may be desired (at the expense
> of job performance and resources utilization for doing encryption).
