    Description

      In Java 9, MapReduce job fails due to missing java.activation module, so we need to configure mapred-site.xml as follows to run MapReduce job:

      <property name="yarn.app.mapreduce.am.admin-command-opts" value="--add-modules java.activation"/>
<property name="mapreduce.map.java.opts" value="--add-modules java.activation"/>
<property name="mapreduce.reduce.java.opts" value="--add-modules java.activation"/>

      I'm thinking it's better to add "--add-modules java.activation" automatically.
