How to increase map and reduce task number during #3 Step Name: Extract Fact Table Distinct Columns

Hi all, I have a cube build very slowly, especially the step 3* Extract Fact Table Distinct Columns*. I checked job log at YARN, found the map and task number is small then previous 2 steps. Could any one tell me how to determine the map and reduce task number to increase job parallel. Thanks!
