Hi JD, FileSystem is a public API but DFSClient is an internal class. For developing Hadoop applications, we should use FileSystem.

Both of these classes are used for connecting a remote client to the namenode in HDFS. So, I wanted to know the advantages of one over the other and which one is suitable for remote-client connection. Regards, JD
