What are some common HDFS commands that can be mapped in the bash files?

bash hadoop hdfs command-line-interface putty

The good practice is to put aliases in .bash_aliases.

For your problem, I'd put alias h="hdfs dfs" in my .bash_aliases file (create it if it doesn't exist)

Most distribs will already have this in their .bashrc file but if it's not there, add

if [ -f ~/.bash_aliases ]; then    . ~/.bash_aliasesfi

in your .bashrc

Now you can either type source .bashrc or restart you terminal and h -ls wille be interpreted as hdfs dfs -ls

Note that cou can also very well put all of your aliases directly in the .bashrc, but I find it more convenient to have all the aliases set appart.

Are there any other useful commands that I can map here?

And you can add what you want so if you run a command really often you can consider adding it in your aliases.

Hope this helps!
