Hi,
I'm trying to implement security on my hadoop data. I'm using Cloudera hadoop
Below are the two specific things I'm looking for
1. Role based authorization and authentication
2. Encryption on data residing in HDFS
I have looked into Kerboroes but it doesn't provide encryption for data
to completion.

The namenode is essentially running bash -c id -Gn hduser and waiting for the
