Before
transferring the data from hard disk location to map method, there is a phase or
method called the ‘Split Method‘. Split method pulls a block of data from HDFS
to the framework. The Split class does not write anything, but reads data from
the block and pass it to the mapper. Be default, Split is taken care by the
framework. Split method is equal to the block size and is used to divide block
into bunch of splits.
