在Shell脚本中运行Hadoop命令

问题描述

我有一个简单的shell脚本，可以用来将日志文件移动到Hadoop集群中.

I have a simple shell script that I'd like to use to move log files into my Hadoop cluster.

当我在Java程序中调用shell脚本时，找不到该脚本"Hadoop命令"，并且我不执行任何操作.

When I invoke the the shell script in my Java program, the script can not be found "Hadoop Commands", and I do not take any action.

例如，我想运行以下命令:

For instance, I would like to run the following command:

#!/bin/bash
hadoop fs -put /home/can/workspace2/myWebApp/tweets.txt /user/training/tweetFolder

我如何以简单的方式解决这个问题?

How can I solve this in a simple manner?

推荐答案

我认为这是PATH问题.检查hadoop的路径:

I believe it's a PATH problem. check the path for hadoop with which:

which hadoop

然后将完整路径放在脚本中.

Then put the full path on your script.
