Hadoop 的运行方式是由配置文件决定的（运行 Hadoop 时会读取配置文件），此外，伪分布式虽然只需要配置 fs.defaultFS 和 dfs.replication 就可以运行（官方教程如此）。(The mode of running Hadoop is determined by the configuration file (the configuration file is read when running Hadoop). In addition, the pseudo distributed can run only by configuring fs.defaultFS and dfs.replication (the official tutorial is the case).)
