Summary: Add reader schema null check for
AvroDeserializationSchema when recordClazz is GenericRecord
Key: FLINK-20853
URL: https://issues.apache.org/jira/browse/FLINK-20853
Project: Flink
Issue Type: Improvement
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Affects Versions: 1.12.0
Reporter: hailong wang
Fix For: 1.13.0
Reader schema can not be null when recordClazz is GenericRecord.
Although its constructor is default, this will cause NPE when reader schema is
null and recordClazz is GenericRecord for the class extends it, such as
RegistryAvroDeserializationSchema.
