Hi @fhueske , thanks for review.
I will update` equals() `and `hashcode() `methods of Row, but I also
noticed that in `JoinOperator` and `KeySelector`, they used `RowComparator` to
compare row elements.
For the unit test, I noticed in `TypeInformationTestBase` there is a`
testHashcodeAndEquals` method already, I will complete this test to add test
case with type info without implementing its own `hashcode ` and `equals`
method.
