在Hadoop2集群中运行WordCount示例时遇到初始化集群错误，尽管ResourceManager、NameNode、NodeManager和DataNode均已成功启动。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

在 hadoop2集群 master1上，执行 HADOOP自带的例子， wordcount 包，命令如下
cd /usr/local/hadoop/hadoop-2.0.2-alpha/share/hadoop/mapreduce
hadoop jar hadoop-mapreduce-examples-2.0.2-alpha.jar wordcount hdfs://192.168.1.33:9000/input hdfs://192.168.1.33:9000/output
出现错误：

但是我通过start-all.sh启动之后，jps查看 master机器上：ResourceManager和NameNode都已启动，slave机器上NodeManager和DataNode也已经启动了，查看启动日志均无报错，但是验证map/reduce时就报这个错误，请指点迷津，不胜感谢
