----------------------------------------
Summary: [JDK9] Add "--add-modules java.activation" to java option
if the Java version is 9 or upper.
Key: MAPREDUCE-7142
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7142
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Akira Ajisaka
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:
{code}
<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"/>
{code}
I'm thinking it's better to add "--add-modules java.activation" automatically.
