             Summary: Kylin should not distribute hive table by random at Step1
                 Key: KYLIN-3278
             Project: Kylin
          Issue Type: Improvement

Hi,Kylin team.

When I upgrade from 2.2.0 to 2.3.0 ,I found that the step.1 "Create 
Intermediate Flat Hive Table" of cube build was much slower than before, 
because Kylin distribute hive table by random when created it in version 2.3.0 
. I wander is it necessary? Because kylin.source.hive.redistribute-flat-table 
was set to true by default, so we will do the distribution job at Step.2 
"Redistribute Flat Hive Table".

Best regards, 
 Chuqian Yu
