> 1. For secure hadoop, configure all secure specific configurations in pxf-env as opposed
to pxf-site.
> 2. Make delegation token property option for PXF when used against secure hadoop. Delegation
token is a complementary means for authentication with hadoop along with Kerberos. There is
not much value in using the delegation token with segment only PXF architecture, as each pxf
jvm will need to establish the token anyway. Simply authenticating with Keberos should be
good enough in such a deployment mode.
