Join queries with order by clause doesn't work
See original GitHub issueHi! Join queries with order by clause doesn’t work
Affected Version
0.23.0, 0.24.0
Description
Queries like (with join and order by clause):
SELECT "T1"."__time"
FROM "SomeTableA" AS "T1"
JOIN "SomeTableB" AS "T2"
ON "T1"."A" = "T2"."B"
ORDER BY "T1"."__time" ASC
Doesn’t work at 0.23.0 and 0.24.0 versions of Druid (but works at 0.22.0). “Doesn’t work” means that query processing ends with exception on broker node:
Error: Unknown exception
Cannot convert query parts into an actual query
org.apache.druid.sql.calcite.rel.CannotBuildQueryException
More detailed log here: broker.log

I think https://github.com/apache/druid/pull/12418 caused it. @somu-imply FYI.
The test case has been added through #13173
