YARN Script Terasort Error

[#1]

Hi Community,

I am trying to run a YARN script to test tune my cluster using teraGen and TeraSort. I have modified the script and got the teraGen part Running with no problems. However I keep getting an error when the teraSort begins:

Below is the error:

And below is the Script

Been at this for a couple of days so any help is more than welcome!

thanks

Ok so I finally found an answer. It seems copying from notepad to vi adds hidden characters had to code everything on vi and I had no issue.
