Linux can boot Linux from a floppy disk or hard drive. When booting Linux from a floppy disk, the boot sector contains code that reads only the first hundreds of blocks of data (of course, depending on the kernel size) to a predetermined memory location. 　　On a Linux boot floppy, there is no system and the kernel has contiguous sectors because it simplifies the boot process. After the floppy disk Boots Linux Linux is loaded, it initializes the hardware and device drivers and then runs Init. Init can start other processes to Http://www.aliyun ....

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 ...
