Invalid user error using chown

I am running into an issue where when I type in sudo chown, I am recieving an invalid user error.

I created a user called clusterUser using the GUI. In the root directory of the computer (/), I created a folder called clusterFiles. I would like to change the home directory of clusterUser to be clusterFiles. I am using this set of commands to change the home directory:

sudo chown clusterUser /clusterFiles
sudo usermod -d /clusterFiles clusterUser

However, when I run the command sudo chown clusterUser /clusterFiles, I get the error invalid user clusterUser.

I know that I have created it becuase I logged into it. Is there something wrong with how I formatted the command?

Edit:

The output of getent passwd | grep 'cluster' yeilds:

rgcluster2blade1:x:1000:1000:RGcluster2Blade1,,,:/home/rgcluster2blade1:/bin/bas‌​h
clusteruser:x:1002:1002:clusterUser,,,:/home/clusteruser:/bin/bash

According to your passwd file, the username is clusteruser with a real name of clusterUser (clusteruser:...:clusterUser...). chown cares only about the username, which has no capital letters.

Use chown clusteruser.
