Hi all, on my company we recently began some projects where we would like to actively use hadoop. For one of them, basically we have implemented a feed service where feed entries (there could be a lot of data because many different users can post feeds), are actually stored in the server filesystem (for the moment only one server) by using Hadoop.S
Such a system needs some security improvements, and I'm wondering what kind of security mechanism is currently provided by Hadoop. For example, only allowed users should be able to access, from the browser, to our service to read data (because they will normally be sensitive data), provided that they have access credentials (authenticated and authorized users). Also, the same data should be secured by using some forms of encryption for the server-to-client data transfer. I read some old posts and discussions inside the hadoop project concerning security, but I am a little confused on what is actually implemented concerning authentication, authorization and encryption, on which version of hadoop, and if something currently provided can match my needs. If someone could point me to the right direction, your help will be very appreciated. Giovanni
