Subject [jira] [Commented] (MAPREDUCE-4417) add support for encrypted shuffle
Date Mon, 23 Jul 2012 22:25:36 GMT

Todd Lipcon commented on MAPREDUCE-4417:
----------------------------------------

bq. PS I thought we had a process for adding things to 1, which was to propose them during
next release planning.

That process was proposed but it hasn't been followed at all. There have been plenty of new
features going into branch-1 without prior discussion.

> 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).
