AvroParquetWriter dataFileWriter = AvroParquetWriter(path, schema); dataFileWriter.write(record); You probabaly gonna ask, why not just use protobuf to parquet The generated pojos extend SpecificRecord which can then be used with AvroParquetWriter. 2) Write the conversion from your pojo to GenericRecord yourself. You can do this either manually or a more generic solution would be to use reflection. However, I encountered difficulties with this approach when I tried to read the data.
