Stefan Richter created FLINK-4374:
-------------------------------------
Summary: GroupReduce Broken for null Date
Key: FLINK-4374
URL: https://issues.apache.org/jira/browse/FLINK-4374
Project: Flink
Issue Type: Bug
Components: DataSet API
Reporter: Stefan Richter
The GroupReduceITCase has an error that allows a problem with {{nul}}l Dates to
go uncovered:
If I set the parallelism to 1 in {{testDateNullException()}} and all keys
actually end up on the same operator, then there is a problem in the
de/serialization.
It seems that {{null}} values are somehow skipped by the serialization process
(e.g. maybe no {{null}} indicator is written), which leads to wrong
deserializations.
