Constructor Detail

### SequenceFileInputFormat

    public SequenceFileInputFormat()

Method Detail

### listStatus

    protected FileStatus[] listStatus(JobConf job)
                               throws IOException

  Description copied from class: `FileInputFormat`
  List input directories. Subclasses may override to, e.g., select only files matching a regular expression.

  Overrides:
    `listStatus` in class `FileInputFormat<K,V>`
  Parameters:
    `job` - the job to list input paths for
  Returns:
    array of FileStatus objects
  Throws:
    `IOException` - if zero items.

### getRecordReader

    public RecordReader<K,V> getRecordReader(InputSplit split,
                                             JobConf job,
                                             Reporter reporter)
                                      throws IOException

  Description copied from interface: `InputFormat`
  Get the `RecordReader` for the given `InputSplit`.

  It is the responsibility of the `RecordReader` to respect record boundaries while processing the logical split to present a record-oriented view to the individual task.

  Specified by:
    `getRecordReader` in interface `InputFormat<K,V>`
  Specified by:
    `getRecordReader` in class `FileInputFormat<K,V>`
  Parameters:
    `split` - the `InputSplit`
    `job` - the job that this split belongs to
  Returns:
    a `RecordReader`
  Throws:
    `IOException`
