The property is mapreduce.framework.name in mapred-site.xml

<property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
</property>

The current property mapred.framework.name is not valid and is not recognized. Thus, the jobs are being submitted in local mode. Locally run jobs are not tracked by jobhistoryserver.

Modify the property name and restart the services.
