That's not quite what pseudo-distributed mode is. You can run regular hadoop jobs on a cluster that consists of one machine, just change the hostname in your hadoop-site.xml file to the real hostname of your machine. If you've got "localhost" in the conf, Hadoop is going to use LocalJobRunner, and that may be related to your issue. I may be wrong on this - I haven't spent much time looking at that code. Take a look at ./src/java/org/apache/hadoop/mapred/JobClient.java for what gets kicked off (for 0.17.1 at least). -- James Moore | [EMAIL PROTECTED] Ruby and Ruby on Rails consulting blog.restphone.com
