---------------------------------------
Summary: 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
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.
