If i have a compressed file of 1GB which is splittable and by default the block size and input split size is 128MB then there are 8 blocks created and 8 input split. When the compressed block is read by map reduce it is uncompressed and say after uncompression the size of the block bbecomes 200MB. But the input split for this assigned is of 128MB, so how is the rest of the 82MB processed.
1. Is it processed by the next input split?
2. Is the same input split size is increased?
