OBR 10.40 Can't open PID file when starting PMDB_Platform_Vertica.service

when starting vertica using Service, HPE_PMDB_Platform_Vertica   and it is not creating vertica pid fle in vertica catalog directory. In order to narrow down the issue, I just had a call with Manjunath and started vertica database directly using admintools and Database is coming UP without any issue and vertica.pid file is being created.  Vertica.pid is always owned by dbadmin user. It looks like service is not considering it since it is not owned by root user. Hence it is failing to start HPE OBR as highlighted below.

New main PID 120242 does not belong to service, and PID file is not owned by root. Refusing.

systemd[1]: Can't open PID file /data/catalog/pmdb/v_pmdb_node0001_catalog/vertica.pid (yet?) after start: No such fil...directory

Failed to start HPE Operation Bridge Reporter Vertica

I have even checked the KM03640804 document for this issue and every thing looks fine.

Kindly any body help on this issue.
