NullPointerException in .CubeHBaseEndpointRPC$1.run

Kylin crew:

I'm still trying to get Kylin working on MapR Hadoop, and now I'm seeing
the following error when trying to run a query through the Kylin web interface.

Building the cube seems to work OK, but this happens at query time.  Any ideas?
