Unable to use "." in column name

[Ben Johnson]

Hi, I have a fairly basic question. I'm attempting to use a "." in a Hive
column name. I must be doing something wrong, because the Hive documentation
says:
"by default column names can be specified within backticks (`) and contain any
Unicode character (HIVE-6013)"
Here's a better breakdown of what I'm doing and the error message I'm receiving.
Thanks for your help!
