What is the difference between DFSClient Protocol and FileSystem class in Hadoop DFS (HDFS). 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.

JD

Hi JD,

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