Check to identify duplicate values at first column in csv file

Hello experts,

I have a requirement where I have to implement two checks on a csv file:

1. Check to see if the value in first column is duplicate, if any value is duplicate script should exit.

2. Check to verify if the value at second column is between "yes" or "no", if it is anything else script should exit.

My input file looks like:
hiring,no
system,yes
hiring,yes
quota,no

OS is solaris.

I have been trying to implement/list my first requirement using awk but without any success, i tried this but there is no output:

Code:
awk 'x[$1]++ == 1 { print $1 " is duplicated"}' FILENAME

awk'x[$1]++FS=","



is not working either, since above file has hiring at two places script should come out.

Please advise.
