Ubuntu custom command to start Hadoop operations

When you do Hadoop, you often need to open the bin directory under Hadoop and enter the command

In Ubuntu we use a custom command to simply implement this command

Open the. bashrc file First

sudo vim ~/.BASHRC

And then add it at the end of the file

Alias hadoopfjsh= '/usr/local/hadoop/bin/hadoop '

That's right. Input hadoopfjsh will call this command directly.

Note After adding to enable this command to take effect immediately using the source ~/.BASHRC run

Enter after you start Hadoop

Hadoopfjsh Dfs-ls try to get the results straight.
