hbase security API

Hi,

It appears that the Kerberos authentication integration into HBase is via JAAS Krb5LoginModule.  That is,
I can setup up the "Client" application context and configure where/how the client Kerberos principle is
authenticated (TGT).  Correct?  If I have a multi-tenant application that performs scans/gets/puts based
on different users, what is the appropriate way to specify the Kerberos principle to use on each thread?
I was thinking that I could use a JAAS callbackHandler to specify the principle to use and then configure
the login module to query a keytab for the principal's password key.  Or do I have to create a Subject and
configure the login module to use the shared state?

What's an application's integration point into specifying what client Kerberos principal to authenticate and use.


Thank you!
