Hello,
I have run into a problem when attempting to run jobs that require
code from multiple jars. The JobConf only allows me to set one jar
file, so the other jars are not copied to the task trackers, and hence
the jobs fail due to the dependencies. Besides merging the jars or
manually copying them to each machine, is there a solution for this?
Try to create lib directory in your jar and put your dependency into
this directory. Contents of the jar's lib directory is added to
classloader during starting map and reduce tasks. Unfortunately it does
not work if you try to use additional libraries in InputReader in this
case classlaoder is not modified.
Retards,
