在hadoop服务器上运行jar命令，例如：[hadoop@hadoop000 lib]$ hadoop jar wxx-hadoop-1.0.jar com.wxx.bigdata.hadoop.mapreduce.wc.WordCountYARNApp /ruozedata/wc/input /ruozedata/wc/output.报如下错误：

如果是伪分布式，就要查看yarn是否启动了。
如果是集群，就要按照如下设置：
 

  yarn.resourcemanager.address
  master:8032


  yarn.resourcemanager.scheduler.address
  master:8030


  yarn.resourcemanager.resource-tracker.address
  master:8031
