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<BytesWritable,BytesWritable>
- Overrides:
getRecordReader
in class SequenceFileInputFormat<BytesWritable,BytesWritable>
- Parameters:
split
- the InputSplit
job
- the job that this split belongs to
- Returns:
- a
RecordReader
- Throws:
IOException
