Why there is a mapreduce.jobtracker.address configuration on YARN?
YARN is the Hadoop second generation that not use the jobtracker daemon anymore, and substitute it with resource manager. But why, on mapred-site.xml hadoop 2 there is an mapreduce.jobtracker.address property? You are correct. In YARN, jobtracker no longer exists. So as part of client configuration you don't have to to specify the property mapreduce.jobtracker.address . In YARN, you should specify the property mapreduce.framework.name to yarn in the config file. Instead of setting up mapreduce.jotracker.address, you need to specify yarn.resourcemanager.address . setting yarn.resourcemanager
