Right now any file compressed with lzop will be processed by one mapper. This is a shame since the lzo algorithm would be very suitable for large log files and similar common hadoop data sets. The compression rate is not the best out there but the decompression speed is amazing. Since lzo writes compressed data in blocks it would be possible to make an input format that can split the files.
