Looks like i had a lucky day and went with this exception through 'all' of those causes. Summary:

• wrong mapreduce.framework.name (yarn) 
• missing mapreduce job-client jars or did not put it as the first dependency in maven ( put hadoop-mapreduce-client-jobclient at the first dependency)
• wrong hadoop version (see Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses-submiting job2remoteClustr )
• my configured 'yarn.ipc.client.factory.class' wasn't in the classpath of the yarn server's (just on the client)
