Todd Lipcon commented on MAPREDUCE-4417:
----------------------------------------
bq. -1 findbugs. The patch appears to introduce 1 new Findbugs (version 1.3.9)
warnings.
Are you going to update the findbugs exclude file for this warning? We can't
commit until this comes back clean.
Otherwise the latest trunk patch looks good.
> 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).
