Uses of InputFormat in org.apache.hadoop.mapred
Classes in org.apache.hadoop.mapred that implement InputFormatModifier and TypeClassDescriptionclassFileInputFormat<K,V> A base class for file-basedInputFormat.classFixedLengthInputFormat is an input format used to read input files which contain fixed length records.classAnInputFormatfor plain text files.classMultiFileInputFormat<K,V> An abstractInputFormatthat returnsMultiFileSplit's inMultiFileInputFormat.getSplits(JobConf, int)method.classInputFormat reading keys, values from SequenceFiles in binary (raw) format.classThis class is similar to SequenceFileInputFormat, except it generates SequenceFileAsTextRecordReader which converts the input keys and values to their String forms by calling toString() method.classA class that allows a map/red job to work on a sample of sequence files.classAnInputFormatforSequenceFiles.classAnInputFormatfor plain text files.Methods in org.apache.hadoop.mapred that return InputFormatModifier and TypeMethodDescriptionJobConf.getInputFormat()Get theInputFormatimplementation for the map-reduce job, defaults toTextInputFormatif not specified explicity.Method parameters in org.apache.hadoop.mapred with type arguments of type InputFormatModifier and TypeMethodDescriptionvoidJobConf.setInputFormat(Class<? extends InputFormat> theClass) Set theInputFormatimplementation for the map-reduce job. -
