You probably haven't reserved any hugepages.
Take a look at the Getting Started Guide (section 2.3.2):
http://dpdk.readthedocs.org/en/v2.2.0/linux_gsg/sys_reqs.html#running-dpdk-applications

Another way is run the setup.sh script, in tools directory.
Options 20 and 21 will do the hugepage reserve for you,
just need to pass the number of hugepages that you want.

Let me know if you have any more issues.
