Cannot run the job on hadoop cluster. only runs using LocalJobRunner

I've submitted a MR job using hadoop jar command with the following command on CDH5 Beta 2

hadoop jar ./hadoop-examples-0.0.1-SNAPSHOT.jar com.aravind.learning.hadoop.mapred.join.ReduceSideJoinDriver tech_talks/users.csv tech_talks/ratings.csv tech_talks/output/ReduceSideJoinDriver/

I've also tried providing the fs name and job tracker url explicitly as below without any success

hadoop jar ./hadoop-examples-0.0.1-SNAPSHOT.jar com.aravind.learning.hadoop.mapred.join.ReduceSideJoinDriver -Dfs.default.name=hdfs://abc.com:8020 -Dmapreduce.job.tracker=x.x.x.x:8021 tech_talks/users.csv tech_talks/ratings.csv tech_talks/output/ReduceSideJoinDriver/

The job runs successfully but is using the LocalJobRunner instead of submitting to the cluster. The output is written to HDFS and is correct. Not sure what I am doing wrong here so appreciate your input. I've also tried explicitly specifying the fs and job tracker as below but have the same result

Re: Cannot run the job on hadoop cluster. only runs using LocalJobRunner

Your job will not read -D parameters unless its designed to use Tool interface and you explicitly use the getConf() function instead of constructing your own Configuration object. Since the source wasn't shared, I cannot tell if it was done.

Alternatively, place proper client configs under /etc/hadoop/conf by following http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM4Ent/4.8.1/Cloudera-Manager-Install... such that the command can find it via the default classpath, and thereby run on the cluster.
