It should support all formats in theory, since it combine on `InputSplit` level which is the result of `inputformat.getSplits`. In other words, split is transparent to inputformat. I've tested it with Sequence, ORC and LZO. but this patch sometimes may not suitable for Parquet since it would not always go through `TableReader`
