在带有ToolRunner和GenericOptionParser的Hadoop上使用Yaml而不是xml配置文件

我正在开发一个MapReduce（hadoop2.6）应用程序，我想使用

yaml

格式，而不是

xml

config格式

比如说

configuration:
  hello: "world"

而不是

<?xml version="1.0"?>
<configuration>
    <property>
        <name>hello</name>
        <value>world</value>
    </property>
</configuration>

当然，如果我尝试这样做，我会得到一个例外：
