testfixer0 updated FLINK-15975:
-------------------------------
Description: The test `testMap` in `HiveGenericUDFTest` may fail due if
HashMap iterates in a different order. `testMap` depends on `getConversion` and
`toFlinkObject` in class `MapObjectInspector`. When the `inspector` is the
instance of `MapObjectInspector`, it can return a `HashMap`. However, `HashMap`
does not guarantee any specific order of entries. Thus, the test can fail due
to a different iteration order. (was: The test `testMap` in
`HiveGenericUDFTest` fails. As you suggested, we'd be better to change
assertions in test code to cater to the indeterminacy. So, I propose a new
proposal. )
