Description

As per the yarn.nodemanager.env-whitelist for the configured values should containers may override rather than use NodeManager's default.

  <property>
    <description>Environment variables that containers may override rather than use NodeManager's default.</description>
    <name>yarn.nodemanager.env-whitelist</name>
    <value>JAVA_HOME,HADOOP_COMMON_HOME,HADOOP_HDFS_HOME,HADOOP_CONF_DIR,CLASSPATH_PREPEND_DISTCACHE,HADOOP_YARN_HOME</value>
  </property>

But only the following containers can override

    whitelist.add(ApplicationConstants.Environment.HADOOP_YARN_HOME.name());
    whitelist.add(ApplicationConstants.Environment.HADOOP_COMMON_HOME.name());
    whitelist.add(ApplicationConstants.Environment.HADOOP_HDFS_HOME.name());
    whitelist.add(ApplicationConstants.Environment.HADOOP_CONF_DIR.name());
    whitelist.add(ApplicationConstants.Environment.JAVA_HOME.name());
