Work Description: kennknowles commented on issue #5544: [BEAM-4449]
Replace project and filter with calc
URL: https://github.com/apache/beam/pull/5544#issuecomment-394885850
Fixed that. From what I can tell, the trait simplification issue lies
entirely within bits we didn't author. The `CalcRemoveRule` tries to convert to
`getTraits()` of a `LogicalCalc` node.
