> The plan contains a HiveTableFunctionScan operator:
> {code:java}
> HiveTableFunctionScan(invocation=[replicate_rows($0, $1)],
> rowType=[RecordType(BIGINT $f0, TIMESTAMP(9) $f1)])
> {code}
> HiveTableFunctionScan is not handled by HiveRelFieldTrimmer nor
> RelFieldTrimmer which suppose to remove unused columns in the
> CalcitePlanner.applyPreJoinOrderingTransforms(...) phase. The whole subtree
> rooted from HiveTableFunctionScan is ignored.
> Whole plan:
> {code:java}
> CBO PLAN:
