------------------------------------
Assignee: Xuannan Su
> Two input AbstractStreamOperator may throw NPE when receiving RecordAttributes
> ------------------------------------------------------------------------------
>
> Key: FLINK-35089
> URL: https://issues.apache.org/jira/browse/FLINK-35089
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Task
> Affects Versions: 1.19.0
> Reporter: Xuannan Su
> Assignee: Xuannan Su
> Priority: Major
> Labels: pull-request-available
>
> Currently the `lastRecordAttributes1` and `lastRecordAttributes2` in the
> `AbstractStreamOperator` are transient. The two fields will be null when it
> is deserialized in TaskManager, which may cause an NPE.
> To fix it, we propose to make the RecordAttributes serializable and these
> fields non-transient.
