Implementing security in hadoop

Question

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 already residing in HDFS.

Are there any other security tools i can go for? has anyone done above two security features in cloudera hadoop.

Please suggest
