[CARBONDATA-3089]
In case of NO_SORT, currently carbon follows task distribution the same way
as
LOCAL_SORT, however, in this case it is better to follow the same task
distribution as other file format does.
Thus, this PR change the task distribution as global sort, which depends on
CSV input format to get the input split and send task based on compute
framework scheduling.
