public class StreamInputFormat
extends org.apache.hadoop.mapred.KeyValueTextInputFormat

An input format that selects a RecordReader based on a JobConf property. This should be used only for non-standard record reader such as StreamXmlRecordReader. For all other standard record readers, the appropriate input format classes should be used.
