I have recently installed CDH 5.1.0 using Cloudera Manager. When using MR2 jobs for testing services it seems my MR jobs are running locally and jobs are not submitted to cluster. I cannot see the jobs submitted in my RM UI also.
When i run Hadoop MR job with my user like hadoop jar /usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples-2.3.0-cdh5.1.0.jar grep /user/sreejith/sample.txt /user/sreejith/output 'a-z' it run locally.
MR logs in console shows INFO mapred.JobClient: Running job: job_local1263402498_0001
My configurations in mapred-site and yarn-site seems to be correct
