> Thanks @viirya ! the new PR looks almost good to me except one nit.
>
> Also comparing to the original patch, we don't have changes to
`HiveRelDecorrelator`, `HiveAggregate` and `HiveSubQueryRemoveRule`. This is
unnecessary because we've shaded Guava within `hive-exec`? (some of the APIs
like `operandJ` do not exist in the Calcite version used by branch-2.3 also).
The change to `HiveAggregate` just to remove unused parameter `groupSets` in
`deriveRowType`. Not related to shading guava, so I don't apply it.
The change from `operand` to `operandJ` in `HiveSubQueryRemoveRule` and
`HiveRelDecorrelator`, cannot apply to branch-2.3 because `operandJ` is not in
calcite 1.10.0. The API was add since calcite 1.17.0
(https://github.com/apache/calcite/commit/d59b639d/).
