Why do I need to source bash_profile every time

Question

I have installed Hadoop and every time I want to run it, first I have to do this:

source ~/.bash_profile

or it won\'t recognize the command

Answer 1

Not sure if this is the best solution but it works.

sudo nano /etc/bashrc and change that, restarted the terminal and it finally remembered with command. Tried ~/.bash_profile and ~/.bashrc without success, just wasn't sourcing it.
