> When dynamic column is enabled, kylin will try to push down group by case when to hbase. However, in the following case, the push down should not be enabled, since currently it's not well supported for CompareTupleFilter to have a child of CompareTupleFilter.
> {code}
> case when (colA = (1=1)) = (colB = (1=1)) then 'XXX'
> {code}
