> Hi , Kylin community.
> I am using "intersect_count" to calculate the conversion rate and want to pushing it down to hive when no cube can answer. But the array format "array[]" is not readable in hive .So I need to add a method in org.apache.kylin.source.adhocquery.HivePushDownConverter in order to replace "array[]" to "array()" when pushing down query to Hive.
> Any suggestions?
