安装完hadoop 2.7.1是否自动有input、output目录，好像没见到要手动创建这两个目录？

谢谢分享！

• WARN hdfs.DFSClient: DFSInputStream has been closed already
• 这个问题解决了吗？
  

OK  找到了

楼主：进入路径/tmp/hadoop-aboutyun/dfs/data，修改VERSION文件
并没有这个目录

非常感谢，照着这两篇文章，成功安装了hadoop2.8.对于最后的那个警告问题，apache官网有问题记录
https://issues.apache.org/jira/browse/HDFS-8099
建议是直接修改源代码，将WARN级别改为DEBUG级别。代码如下：
diff --git hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/DFSInputStream.java hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/DFSInputStream.java
