Had sent Eric a response, copying it here. Breakpoint need to be in method ExHbaseScanSQTaskTcb::work for traf tables. Other ::work method in that file are for native hbase tables, and other specialized scan access.

You could equally well try putting a breakpoint at ExHbaseScanTaskTcb::work. The work method is called at least once each time the statement is executed. A simple way to get started is to test using sqlci on platform. You can just "gdb sqlci", then "start" then "b ExHbaseScanTaskTcb::work". For simple serial plans you should get a hit in the sqlci process itself. (If you have a parallel plan, then this method would get hit in the ESPs instead.)
