# Which issue does this PR close? Fixes #5970. This is an alternative to #6009. # Rationale for this change `UnionExec` shall be a simple node and not perform some optimizations on its own. If repartition / partition concatenation is desired, then there should be an optimizer pass for that. Being a simple node avoids confusion and optimizer bugs like #5970. # What changes are included in this PR? Remove the entire "partition aware" logic from `UnionExec` # Are these changes tested? 1. Existing tests pass 2. Test for #5970 passes. # Are there any user-facing changes? Less bugs. -- This is an automated message from the Apache Git Service.
