Hi Tanton, As of Hadoop 0.17, you can add jars on the command line: bin/hadoop jar -libjars foo.jar,baz.jar your-job.jar Pre 0.17, you can do this in your job configuration: DistributedCache.addFileToClassPath(new Path("/lib/foo.jar"), jobconf); And then upload foo.jar before running your job: bin/hadoop fs -put foo.jar /lib/foo.jar -Stuart
