Have anyone dealt with the similar JR to DFS conversion.. ?? pls explain ... Still, what do you mean by DFS? Distributed File System? How do you "use" it (ie. Apache Hadoop) in your client applications, what is the interface you use? Direct filesystem access, webdav, Hadoop API, etc? Jackrabbit obviously mainly provides the JCR API as interface, but it also provides a stable WebDAV filesystem-like mapping (only nt:file/nt:folder in the repository) that can be mounted as file system. The backend part of Jackrabbit (persistence managers, datastore) is optimized for performance and pure JCR usage, it is an integral part of Jackrabbit's internal architecture. If you want to connect existing datasources via JCR, the Jackrabbit SPI interface is thought to make development of such connectors/adaptors simpler.
