Hadoop dfs -ls command

–1 vote

I have Hadoop installed in this location:


Here I am listing out the files present in my dfs directory. So for this, I used the command: user1@ubuntu:/usr/local/hadoop$ bin/hadoop dfs -ls

This gave me the correct result.

But after that, I tried the same command in a different manner

user1@ubuntu:/usr/local/hadoop$ hadoop dfs -ls

I again got the same result.

Could anyone explain me that why I'm getting the same result despite of executing the commands from different folders. I hope you understand my question, I just want to know the difference between the two commands:

1. user1@ubuntu:/usr/local/hadoop$ bin/hadoop dfs -ls

2. user1@ubuntu:/usr/local/hadoop$ hadoop dfs -ls

In your case there is no difference between the two commands because it looks like that you set /usr/local/hadoop/bin as HADOOP_HOME path in the .bashrc file.

Since in unix we can execute an executable file in two ways, either by giving the absolute/relative path or commands in system's executable path. 

So, when you execute - "bin/hadoop dfs -ls" , it will take you inside the directory /usr/local/hadoop. If you remove the HADOOP_HOME path from the .bashrc file, then you will not get the same result.
