-Re: What is the difference between Hdfs and DistributedFileSystem?

Hadoop has two sets of APIs:
- FileSystem.java - this is the older API and more widely used. This
defines both the application API and the API that the concrete file systems
must implement (such as DistributedFileSystem, LocalFileSystem,
- FileContext.java and AbstractFileSystem.java - these are new APIs. The
goal was to divide the Hadoop API into two - application API in
FileContext.java and file system implementation interface
AbstractFileSystem.java. More details -
Hdfs.java is the newer implementation of AbstractFileSystem.java.
DistributedFileSystem.java implements the older API FileSystem.java.
