Muhammad Gelbana closed DRILL-5515.
-----------------------------------
Resolution: Invalid
What I posted is NOT the equivalent form for the "IS DISTINCT FROM" clause.
> "IS NO DISTINCT FROM" and it's equivalent form aren't handled likewise

> The following query fails to execute
> {code:sql}SELECT * FROM (SELECT `UserID` FROM `dfs`.`path_ot_parquet` tc)
> `t0` INNER JOIN (SELECT `UserID` FROM `dfs`.`path_ot_parquet` tc) `t1` ON
> (`t0`.`UserID` IS NOT DISTINCT FROM `t1`.`UserID`){code}
> and produces the following error message
> {noformat}org.apache.drill.common.exceptions.UserRemoteException:
> UNSUPPORTED_OPERATION ERROR: This query cannot be planned possibly due to
> either a cartesian join or an inequality join [Error Id:
> 0bd41e06-ccd7-45d6-a038-3359bf5a4a7f on mgelbana-incorta:31010]{noformat}
> While the query's equivalent form runs fine
> {code:sql}SELECT * FROM (SELECT `UserID` FROM `dfs`.`path_ot_parquet` tc)
> `t0` INNER JOIN (SELECT `UserID` FROM `dfs`.`path_ot_parquet` tc) `t1` ON
> (`t0`.`UserID` = `t1`.`UserID` OR (`t0`.`UserID` IS NULL AND `t1`.`UserID` IS
> NULL)){code}
