WebLempel–Ziv–Oberhumer ( LZO) is a lossless data compression algorithm that is focused on decompression speed. [1] Design [ edit] The original "lzop" implementation, released in 1996, was developed by Markus Franz Xaver Johannes Oberhumer, based on earlier algorithms by Abraham Lempel and Jacob Ziv. WebJun 26, 2024 · Map task is not able to split the LZO compressed file so it uses the whole file as one input split which means only one Map task will process the whole file. In order to make LZO file splittable you will have to run indexer. You can run lzo indexer as a Java program or as a MapReduce job. Running lzo indexer as Java program
