getClassSchema()) . build(); This required using the AvroParquetWriter.Builder class rather than the deprecated constructor, which did not have a way to specify the mode. The Avro format's writer already uses an "overwrite" mode, so this brings the same behavior to the Parquet format. ParquetWriter parquetWriter = AvroParquetWriter. builder(file). withSchema(schema).withConf(testConf).build(); Schema innerRecordSchema = schema.

I managed to resolve the problem. There is an issue when call super.open(fs, path) at the same time creating AvroParquetWRiter instance during write process. The open event already create a file and the writer is also trying to create the same file but not able to because file already exists.

Scio supports reading and writing Parquet files as Avro records or Scala case classes. Also see Avro page on reading and writing regular Avro files.. Avro Read Parquet files as Avro The AvroParquetWriter already depends on Hadoop, so even if this extra dependency is unacceptable to you it may not be a big deal to others: You can use an AvroParquetWriter to stream directly to S3 by passing it a Hadoop Path that is created with a URI parameter and setting the proper configs. GitHub Gist: star and fork hammer's gists by creating an account on GitHub. 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.
