Uses of InputFormat in org.apache.hadoop.mapreduce.lib.db

Subclasses of InputFormat in org.apache.hadoop.mapreduce.lib.db

class	DataDrivenDBInputFormat<T extends DBWritable> A InputFormat that reads input data from an SQL table.
class	DBInputFormat<T extends DBWritable> A InputFormat that reads input data from an SQL table.

Uses of InputFormat in org.apache.hadoop.mapreduce.lib.input

Subclasses of InputFormat in org.apache.hadoop.mapreduce.lib.input

class	CombineFileInputFormat<K,V> An abstract InputFormat that returns CombineFileSplit's in getSplits(JobContext) method.
class	DelegatingInputFormat<K,V> An InputFormat that delegates behavior of paths to multiple other InputFormats.
class	FileInputFormat<K,V> A base class for file-based InputFormats.
class	KeyValueTextInputFormat An InputFormat for plain text files.
class	NLineInputFormat NLineInputFormat which splits N lines of input as one split.
class	SequenceFileAsBinaryInputFormat InputFormat reading keys, values from SequenceFiles in binary (raw) format.
class	SequenceFileAsTextInputFormat This class is similar to SequenceFileInputFormat, except it generates SequenceFileAsTextRecordReader which converts the input keys and values to their String forms by calling toString() method.
class	SequenceFileInputFilter<K,V> A class that allows a map/red job to work on a sample of sequence files.
class	SequenceFileInputFormat<K,V> An InputFormat for SequenceFiles.
class	TextInputFormat An InputFormat for plain text files.

Method parameters in org.apache.hadoop.mapreduce.lib.input with type arguments of type InputFormat

static void	MultipleInputs.addInputPath(Job job, Path path, Class<? extends InputFormat> inputFormatClass) Add a Path with a custom InputFormat to the list of inputs for the map-reduce job.
static void	MultipleInputs.addInputPath(Job job, Path path, Class<? extends InputFormat> inputFormatClass, Class<? extends Mapper> mapperClass) Add a Path with a custom InputFormat and Mapper to the list of inputs for the map-reduce job.

Uses of InputFormat in org.apache.hadoop.mapreduce.lib.partition

Methods in org.apache.hadoop.mapreduce.lib.partition with parameters of type InputFormat

K[]	InputSampler.Sampler.getSample(InputFormat<K,V> inf, Job job) For a given job, collect and return a subset of the keys from the input data.
K[]	InputSampler.SplitSampler.getSample(InputFormat<K,V> inf, Job job) From each split sampled, take the first numSamples / numSplits records.
K[]	InputSampler.RandomSampler.getSample(InputFormat<K,V> inf, Job job) Randomize the split order, then take the specified number of keys from each split sampled, where each key is selected with the specified probability and possibly replaced by a subsequently selected key when the quota of keys from that split is satisfied.
K[]	InputSampler.IntervalSampler.getSample(InputFormat<K,V> inf, Job job) For each split sampled, emit when the ratio of the number of records retained to the total record count is less than the specified frequency.
