Re: What is the difference between Hdfs and DistributedFileSystem?

yes, yes , and YES !  The use of alternative file systems to HDFS exciting
part of the hadoop ecosystem, allowing us to plug mapreduce applications
into different storage backends.  Lost of folks in the hadoop community are
working hard to democratize storage on Hadoop.

Take a moment to read a scan some of these article to get an idea of how
modular the hadoop stack really is, and how broad the ecosystem is in terms
of storage backends.
