Maximilian Michels commented on FLINK-2236:
-------------------------------------------
This still needs to be fixed on the master. Changes have only been reverted for
the upcoming 0.9.0 release.
> RowSerializer and CaseClassComparator are not in sync regarding Null-Values

> Key: FLINK-2236
> URL: https://issues.apache.org/jira/browse/FLINK-2236
> Project: Flink
> Issue Type: Bug
> Reporter: Aljoscha Krettek
> Priority: Blocker
>
> The RowSerializer was recently updated to allow it to handle null values.
> This changes the binary layout of the serialised data. CaseClassComparator,
> which is used for comparison, is not aware of this new layout and therefore
> fails. The problem only occurs when a key is long enough to exceed the
> normalised-key length, that's why the tests fail to notice the bug.
> I think the solution is to modify all Tuple-like serializers/comparators
> (TupleComparatorBase, CaseClassComparator, TupleSerializer,
> CaseClassSerializer, RowSerializer) to handle null-values, thus bringing the
> binary format in sync again.
