> 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".
