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.

指定者:

getRecordReader 在接口中 InputFormat<Text,Text>

覆盖:

getRecordReader 在类中 KeyValueTextInputFormat

参数:

genericSplit - the InputSplit

job - the job that this split belongs to

返回:

a RecordReader

抛出:

IOException
