  Is it possible to submit MapReduce job from slave node or can we submit it just from the master?

  We can run jobs from any machine in the cluster so long as each node has the proper Resource Manager location property configured. So long as we have a connection to the server (that is, no firewalls are in the way) and Hadoop is configured with the proper node manager and namenode, we can submit a job from any node.

  Yes, we can submit a job from any machine in the cluster as long as each node has the proper jobtracker location property configured. Make sure mapred.job.tracker is configured on the slave to the master’s host and port (master.com:8090) you can confirm on a connection using telnet host port.
