ParquetReadSupport

abstract class ParquetReadSupport[T] extends ReadSupport[T] with Serializable

Parquet read support used by org.apache.parquet.hadoop.ParquetInputFormat to read values from parquet input. User must define record schema and parquet tuple converter that permits to convert parquet tuple to user defined type For case class types, we provide a macro to generate the schema and read support: com.twitter.scalding.parquet.tuple.macros.Macros.caseClassParquetReadSupport
