hbase region server error: This is supposed to be overridden by subclasses

I installed the latest version of mapr (3.1.1.26113.GA) using quickinstall on RHEL 6.5. Everything comes up ok, but the HBASE region server doesnt (NFS gateway is also goes down, hope no dependency on that). <BR>
I am using OpenJDK 7 which was installed along with MapR.
In hbase logs I can see error:

There are several discussion on the web related to files generated using protobuf 2.4.1 ([here][1])
There is a newer version on hbase at apache, but dont think I can just use it with MapR directly. Any help ?
