      Description

      The jobtracker hangs and jobtracker info server throws Internal Server Error when until task initialization a exception will be thrown.
      Future jobs will no processed and also the job info server does not show any information since it throws a a http 500.

      This is a show blocker especially when hadoop is shell script driven.
