本文详细介绍了在运行Hadoop MapReduce实例时遇到的ERRORsecurity.UserGroupInformation:PriviledgedActionException异常，并提供了上传指定文件至HDFS的解决方法。通过此教程，您将了解如何成功运行MapReduce任务并解决常见错误。

运行Hadoop mapreduce 实例：

         bin/hadoop jar ./share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar wordcount /input /output

报出ERROR security.UserGroupInformation: PriviledgedActionException 这个异常。原因是input HDFS未创建

解决方法：

上传一个指定文件，比如hbase中的readme.txt文件。

hadoop dfs -put /opt/README.txt /input

运行结果：
