* If it is Data then we just take its format (TEXT or BINARY)
* If it is intermediate lop then it is always BINARY
* since we assume that all intermediate computations will be in Binary format
* 2) Note that Reblock job will never have any instructions in the mapper
* => the input lop (if it is other than Data) is always executed in a different job
