Keys to the Kingdom - Access to All Data Within #Hadoop

Get your tickets, they ain't cheap.

But once you've got them, you've got keys to the kingdom.

All inclusive access to your favorite rides.

I'm talkinga about Hadoop.

Once you have access to the Cluster, you've got the keys to all the data present.

Because from the best of my knowledge there are no other restrictions on the server to restrict access.

You can go surfing for whatever data you want.

No big bad DBA to block your access with roles.

The way to restricts sensative data is to place on different cluster.

And what about encrypting the data, sure why not.

Except what value does that bring.

Correct me if I'm wrong but how does one block access to specific data contained within Hadoop?
