   The  [javadoc for DatumWriter](https://avro.apache.org/docs/1.7.6/api/java/org/apache/avro/file/DataFileWriter.html#append(D)
   ) says: 
   
   "Stores in a file a sequence of data conforming to a schema. The schema is stored in the file with the data. Each datum in a file is of the same schema."
   
   Your test case has records with different schema being written to the same file. 
   
   Please try using the [GenericDatumReader construtor](https://avro.apache.org/docs/1.8.2/api/java/org/apache/avro/generic/GenericDatumReader.html#GenericDatumReader(org.apache.avro.Schema,%20org.apache.avro.Schema)) which specifies both the reader/writer schema. 
   GenericDatumReader(Schema writer, Schema reader)
