Description
It would be nice if can expose the HDFS filesystem using the NFS protocol.
There are a couple of options that I could find:
1. Use a user space C-language-implementation of a NFS server and then use the libhdfs API to integrate that code with Hadoop. There is such an implementation available at http://sourceforge.net/project/showfiles.php?group_id=66203.
2. Use a user space Java implementation of a NFS server and then integrate it with HDFS using Java API. There is such an implementation of NFS server at http://void.org/~steven/jnfs/.
I have experimented with Option 2 and have written a first version of the Hadoop integration. I am attaching the code for your preliminary feedback. This implementation of the Java NFS server has one limitation: it supports UDP only. Some licensing issues will have to be sorted out before it can be used. Steve (the writer of the NFS server implemenation) has told me that he can change the licensing of the code if needed.
