Using Lzo compression algorithms in Hadoop reduces the size of the data and the disk read and write time of the data, and Lzo is based on block chunking so that he allows the data to be decomposed into chunk, which is handled in parallel by Hadoop. 　　This feature allows Lzo to become a very handy compression format for Hadoop. Lzo itself is not splitable, so when the data is in text format, the data compressed using Lzo as the job input is a file as a map. But s ...
