> ARRAY[m1] = ARRAY[m2] is FALSE although m1 = m2 is TRUE for the same two maps

> Key: FLINK-41321
> URL: https://issues.apache.org/jira/browse/FLINK-41321
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Planner
> Affects Versions: 2.4.0
> Reporter: sepuri sai krishna
> Priority: Major
>
> Two maps holding the same entries in a different order compare equal.
> Wrapping each one in an array
> reverses the answer.
> {code:sql}
> SELECT MAP['a',1,'b',2] = MAP['b',2,'a',1]; -- TRUE
> SELECT ARRAY[MAP['a',1,'b',2]] = ARRAY[MAP['b',2,'a',1]]; -- FALSE
> {code}
> Same data, two answers depending on whether the value is a map or an array of
> maps, with no error
> and no warning. Also reproduced with both values arriving from a table source
> rather than as
> literals.
> Not FLINK-41013: that one's wrong results are all the sign of zero, and there
> is no FLOAT or DOUBLE
> in this query.
