[GitHub] [kylin] zhangayqian commented on pull request #1599: KYLIN-4860 Fix union all error

   There is a problem when `unionRel` calculates the `columnRowType`. The current algorithm directly combines the left and right `sourceCols` into an array with the length of 2 as the `sourceCols` of `unionRel`. However, according to the design, it should be equal to the left or right `sourceCols`.
