> Currently, isSplittable method of FileInputFormat always returns true. For some applications,
it becomes necessary that the map task process entire file, rather than a block. Therefore,
splittability of input (i.e. block-level split vs file-level-split) should be controllable
by user via a configuration variable. The default could be block-level split, as is.
