staging directory. This is the jar that you specified to your job conf, or I
believe that it tries to guess the jar based off of the Mapper class and the
Reducer class but I am not sure of that. Once th
Anyone knows the mechanism that hadoop use to load Map and Reduce class on
the remote node
where the JobTracker submit the tasks?
In particular, how can hadoop retrieves the .class files ?
