What's the difference among hadoop streaming, hadoop pipe, and hadoop online (hop), a pipelining version developed by UC Berkeley? 2. In the current hadoop trunk, where could we find hadoop-streaming.jar? Further -- may I have an example which teaches me how to use hadoop-streaming feature? Thanks a lot! -Rita :) --_000_C8AD550A1D8FBamarsriyahooinccom_--
