InputFormat
Hadoop relies on the input format of the job to do three things:1. Validate the input configuration for the job (i.e., checking that the data is there).2. Split the input blocks and files into logical chunks of type InputSplit, each of which is assigned to a map task for processing.3. Create the RecordReader implementation to be used to create key/value pairs from the raw InputSplit. These pairs are sent one by one to their mapper.
A RecordReader uses the data within the boundaries created by the input split to generate key/value pairs. In the context of file-based input, the “start” is the byte position in the file where the RecordReader should start generating key/value pairs. The “end” is where it should stop reading records. These are not hard boundaries as far as the API is concerned—there is nothing stopping a developer from reading the entire file for each map task. While reading the entire file is not advised, reading outside of the boundaries it often necessary to ensure that a complete record is generated
