> Currently, after operator tree is processed, the generated works with union operators will go through {{GenSparkUtils::removeUnionOperators}}, which will clone the original operator plan associated with the work, and remove union operators in it. This caused some issues as seen, for example, in HIVE-7870. This JIRA is created to find out whether it's possible to just remove the union operators in the original plan.
