All, I have a use-case where I need to crunch a large amount of data and push to the results (comparatively a smaller set) to a mysql db at a remote location. As per security concerns, only SSH ports are open. I tried using Java Secure Channel [1] in combination with some custom JDBC code from the reducers.
Can anyone comment on the performance of DBOutputFormat? Have there been any efforts to tunnel this through SSH? This is going to be an expensive operation; any suggestions would be welcome. [1] http://www.jcraft.com/jsch/ --- Gautam Singaraju
