Qingsheng Ren created FLINK-20459: ------------------------------------- Summary: Handle null message correctly in JSON RowData deserializer Key: FLINK-20459 URL: https://issues.apache.org/jira/browse/FLINK-20459 Project: Flink Issue Type: Bug Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile) Reporter: Qingsheng Ren
Currently if the input message of the `deserialize()` method is null and the deserializer is not ignoring parse errors, `new String(message)` in the exception part will lead to an NPE. A possible solution is returning null directly if the input message is null, but I'm not sure if this is a correct behavior since a null message can be treated as a "corrupted" message which cannot be deserialized as JSON and should lead to an exception. -- This message was sent by Atlassian Jira (v8.3.4#803005)
