Description

  /**
   * Default CLASSPATH for YARN applications. A comma-separated list of
   * CLASSPATH entries
   */
  public static final String[] DEFAULT_YARN_APPLICATION_CLASSPATH = {
      "$HADOOP_CONF_DIR", "$HADOOP_COMMON_HOME/share/hadoop/common/*",
      "$HADOOP_COMMON_HOME/share/hadoop/common/lib/*",
      "$HADOOP_HDFS_HOME/share/hadoop/hdfs/*",
      "$HADOOP_HDFS_HOME/share/hadoop/hdfs/lib/*",
      "$YARN_HOME/share/hadoop/mapreduce/*",
      "$YARN_HOME/share/hadoop/mapreduce/lib/*"};

It should have share/yarn/ and MR should add the share/mapreduce/ (another JIRA?)
