本人安装的hadoop版本是2.4.0的,但每次执行命令时都会显示下面的信息
hadoop@VM_160_34_centos:/usr/local/hadoop-2.4.0> hadoop dfs -ls . DEPRECATED: Use of this script to execute hdfs command is deprecated. Instead use the hdfs command for it. ls: `.‘: No such file or directory
原来从0.21.0版本以后,hadoop 命令换成了hdfs命令,上面的命令如同下面的命令:
hdfs dfs -ls // 这时就没有错误了
hadoop@VM_160_34_centos:/usr/local/hadoop-2.4.0> hdfs dfs -ls // Found 2 items drwxr-xr-x - hadoop supergroup 0 2014-08-29 21:30 /in drwx------ - hadoop supergroup 0 2014-08-29 15:03 /tmp
同样:
hadoop@VM_160_34_centos:/usr/local/hadoop-2.4.0> hadoop dfs -put ./input in DEPRECATED: Use of this script to execute hdfs command is deprecated. Instead use the hdfs command for it. put: `in‘: No such file or directory
改为:
hadoop@VM_160_34_centos:/usr/local/hadoop-2.4.0> hdfs dfs -put input/README.txt /t
并且要使用绝对路径必须以 / 头 。好像Hadoop 里面也没有工作目录一说
如:
hadoop@VM_160_34_centos:/usr/local/hadoop-2.4.0> hdfs dfs -mkdir test5 mkdir: `test5‘: No such file or directory
加上/ 就能成功
hadoop@VM_160_34_centos:/usr/local/hadoop-2.4.0> hdfs dfs -mkdir /test4
DEPRECATED: Use of this script to execute hdfs command is deprecated.
