Stefan Richter reassigned FLINK-4374: ------------------------------------- Assignee: Timo Walther > 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 > Assignee: Timo Walther > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
