Hi Nitin, thank you for the answer.
Your second option will be the most feasible, and I think that this not
hadoop-aware, but its a general Tomcat configuration, am I right?
Could you please link me some doc about this configuration?
Thanks a lot!

Subject: Re: Using certificates to secure Hadoop
on network level easy way would be you host your entire infrastructure into
a private network with just one internet facing gateway via which your
client can access your webservice. And in case you need to access internet
for hadoop/oozie then you can setup a NAT
this will be like building your private cloud infra with different internet
other way would be you build your own certificate based authentication
library. (we used to have this @ yahoo where we used to restrict access to
server having certificate only)

Ive been asked to check whether is possible to use certificates to secure
the connection between Hadoop and Oozie and the external world or not.
Case is this:
We have to develop a webservice to run Oozie workflows and access HDFS, so
that there will be just one interface between the cluster and a user web
Current security scenario does not allow to use Kerberos to authenticate the
users, so we were thinking about using certificates, distributed through the
Tomcat stack (as show on the following diagram).
The idea is that only a client (in this case the client would be the Java
WebService the blue box) with the right certificate could talk to the
Hadoop / Oozie machines.
Is it possible to achieve this scenario?
If so, is there a whitepaper on the Internet that shows how to do this?
If not possible, what do you think would be the best security solution not
using Kerberos (example, firewall sec., IP security, )?
Thank you very much, have a nice day!
