I. Introduction We often see some similar in the program disassembled code 0 × 32118965 this address, the operating system called linear address, or virtual address. What is the use of virtual address? Virtual address is how to translate into physical memory address? This chapter will give a brief account of this. 1.1 Linux Memory Addressing Overview Modern operating systems are in 32-bit protected mode. Each process can generally address 4G of physical space. But our physical memory is generally hundreds of M, the process can get 4 ...

Hadoop cluster can run three modes? Stand-alone (local) mode pseudo-distributed mode fully distributed mode 2. stand-alone (local) mode attention points? There is no daemon in standalone mode, everything runs on a single JVM. There is also no DFS here, using a local file system. Stand-alone mode is suitable for running MapReduce programs during development, which is also the least used mode. Pseudo-distribution
