You should not use LocalJobRunner. Make sure that the mapred.job.tracker property does not point to 'local' an instead to your job-tracker host and port.
*But before that* as Sandy said, your client machine (from where you will be kicking of your jobs and apps) should be using config files which will have your cluster's configuration. This is the alternative that you should follow if you don't want to bundle the configs for your cluster in the application itself (either in java code or separate copies of relevant properties set of config files.) This was something which I was suggesting early on to just to get you started using your cluster instead of local mode. By the way have you seen the following link? It gives you step by step information about how to generate config files from your cluster specific to your cluster and then how to place them and use the from any machine you want to designate as your client. Running your jobs form one of the datanodes without proper config would not work. https://ccp.cloudera.com/display/FREE373/Generating+Client+Configuration Regards, Shahab On Tue, Aug 13, 2013 at 1:07 PM, Pavan Sudheendra <pavan0...@gmail.com>wrote: > Yes Sandy, I'm referring to LocalJobRunner.
