Class HiveOutputFormatImpl<K extends org.apache.hadoop.io.WritableComparable<K>,V extends org.apache.hadoop.io.Writable>

java.lang.Object
  org.apache.hadoop.hive.ql.io.HiveOutputFormatImpl<K,V>

All Implemented Interfaces:

org.apache.hadoop.mapred.OutputFormat<K,V>

public class HiveOutputFormatImpl<K extends org.apache.hadoop.io.WritableComparable<K>,V extends org.apache.hadoop.io.Writable>
extends Object
implements org.apache.hadoop.mapred.OutputFormat<K,V>

Hive does not use OutputFormat's in a conventional way, but constructs and uses the defined OutputFormat for each table from FileSinkOperator. HiveOutputFormatImpl is used for basic setup, especially for calling checkOutputSpecs().
