----------------------------------
Summary: 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
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 serialization and these
fields non-transient.
