我在向Yarn提交工作时遇到异常：

java.net.ConnectException: Call From sparkstandalone.abc.com/127.0.0.1 to localhost:9000 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused

我无法确定问题的确切位置。 资源管理器（Yarn）正在运行。下面是我的yarn-site.xml
