MR2 job is not triggered, YarnClientProtocolProvider returned null

[ Edited ]

I am running a mapreduce application in a multi-node cluster, My application is not launching a mapreduce job as its not able to pickup org.apache.hadoop.mapred.YarnClientProtocolProvider as the ClientProtocolProvider - returned null protocol

 

In return its picking up LocalClientProtocolProvider, where that machine doesn't have all the hadoop services running.

How do we set application to use YarnClientProvider instead of LocalclientProtocolProvider. ??

After Map has finsihed 100% reduce is never started , why is that ??

Any help or sugestions would be appreciated.

Thanks

Re: MR2 job is not triggered, YarnClientProtocolProvider returned null

[ Edited ]

I figured out what the issue was. My configuration object was not able to get mapreduce.framework.name as "yarn" from mapred-site.xml. So I was overiding mapreduce.framework.name in driver. So that it can pick YarnClientProtocolProvider instead of LocalClientProtocolProvider. 

 

When yarn is picked up it launched mapreduce job.
