In this section we will delve into the filesystem class of Hadoop-an important interface for interacting with the file system of Hadoop. While we are only focusing on the implementation of HDFS, we generally pay attention to the portability of code between filesystem different sub-class file systems when coding. This is very useful, for example, you can easily use the same code directly on your local file s
