> GroupReduce Broken for null Date
> --------------------------------
>
> Key: FLINK-4374
> URL: https://issues.apache.org/jira/browse/FLINK-4374
> Project: Flink
> Issue Type: Bug
> Components: API / DataSet
> Reporter: Stefan Richter
> Assignee: Timo Walther
> Priority: Major
> Labels: stale-assigned
>
> The GroupReduceITCase has an error that allows a problem with {{null}} 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.
