You have a few options, here's two:

  • Configure a crontab job to run your job every hour, something like (you'll need to fully qualify the path to hadoop and the jar itself):
  0 * * * *   /usr/lib/hadoop/bin/hadoop jar /path/to/jar/log.jar
  • Run an OOZIE server and configure a coordinator to submit the job on an hourly basis. More effort that the above suggestion but worth a look.
