ERROR security.UserGroupInformation: PriviledgedActionException 问题解决

来源：互联网发布：怎么开家淘宝店编辑：程序博客网时间：2024/05/21 12:43

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：
