MultipleInputsFileSplitInputFormat

public class FileSplitInputFormat
extends CompositeInputFormat<org.apache.hadoop.io.NullWritable,org.apache.hadoop.mapred.FileSplit>
implements org.apache.hadoop.mapred.JobConfigurable

A CompositeInputFormat that only provides the source FileSplits as its values so mapreduce components can read the data directly using its internal input format.

Description copied from class: CompositeInputFormat

Creates a record reader instance. The returned record instance can be a wrapper of the internalInputFormat's record reader. This method is called after getRecordReader(). If the internalInputFormat is a CombineFileInputFormat subclass, this method can be called as many times as paths are contained in the CombineFileSplits.

Specified by:

getDelegateRecordReader in class CompositeInputFormat<org.apache.hadoop.io.NullWritable,org.apache.hadoop.mapred.FileSplit>

Parameters:

split - a FileSplit instance

conf - the job configuration

reporter - a Reporter instance

Returns:

a RecordReader instance.

Throws:

java.io.IOException
