In a nutshell

This project provides a library that reads Parquet files into Java objects.

final Path path = new Path("/data/parquet/part-0000.parquet");
final Configuration conf = new Configuration();
try (final ParquetReader<Row> reader = RowParquetReader
        .builder(HadoopInputFile.fromPath(path, conf)).build()) {
    Row row = reader.read();
    while (row != null) {
        System.out.println(row.getValues());
        row = reader.read();
    }
}

For installation, usage examples, data type mapping, and the API reference, see the User Guide.
