As example to see the content of a Parquet file- $ hadoop jar /parquet-tools-1.10.0.jar cat /test/EmpRecord.parquet This is where both Parquet and Avro come in. The following examples assume a hypothetical scenario of trying to store members and what their brand color preferences are. For example: Sarah has an This is the schema name which, when combined with the namespace, uniquely identifies the schema within the store. In the above example, the fully qualified name for the schema is com.example.FullName.

In this case the number 4. So we will use a "lookup table" called "numbers:" to store all of these different die configurations and simplify our code.

Here, we’ll be making changes to the “Cloud Configuration” and “WLAN Configuration” sections to correspond with the GCP project we set up earlier.

2016-04-05 To write the java application is easy once you know how to do it. Instead of using the AvroParquetReader or the ParquetReader class that you find frequently when searching for a solution to read parquet files use the class ParquetFileReader instead. The basic setup is to read all row groups and then read all groups recursively.

Query and export Avro data to a CSV file. In this section, you query Avro data and export it to a CSV file in Azure Blob storage, although you could easily place the data in other repositories or data stores. The builder for org.apache.parquet.avro.AvroParquetWriter accepts an OutputFile instance whereas the builder for org.apache.parquet.avro.AvroParquetReader accepts an InputFile instance. This example illustrates writing Avro format data to Parquet. Avro is a row or record oriented serialization protocol (i.e., not columnar-oriented).
