Hi, In M/R when you need an extra jar to use do you add the jar into the class path by calling: DistributedCache.addFileToClassPath(dfs-path-to-jar);
I imagine that the register command does something similar under the covers but I was just looking for a way to have the UDF load its own dependency jar and thus not leaving it up to the user to remember to issue the second register command (for the dependency jar) on it own.
