Hi Pravin,
Thanks for the response.
I have changed the value to 0.
cat /proc/sys/kernel/randomize_va_space
0
Tried running dpdk sample application (helloworld ) before running my
application but still same warning is reported.
The sample application is not starting up.
When I tired with valgrind from https://github.com/bisdn/valgrind-hugepages
application getting crashed.
Am I missing any other configuration?

DPDK documentation says so for multi-process case.
* The multi-process feature requires that the exact same hugepage memory
mappings be present in all applications. The Linux security feature -
Address-Space Layout Randomization (ASLR) can interfere with this mapping, so
it may be necessary to disable this feature in order to reliably run
multi-process applications.

Hi Pravin,
Randomization is not turned off.
cat /proc/sys/kernel/randomize_va_space
2
Do I need to turn off the randomization?

Is randomization turned off ?
echo 0 > /proc/sys/kernel/randomize_va_space
