Error 9: validating dhclient is not running

marcosarmasmarcosarmas Community Edition User

I'm installing vertica on single node, I'm using the Management Console wizard and I have this error in the "Validating Vertica Requirements" step:
Error:Test: validating dhclient is not running : ERROR 9: Process dhclient is running
My OS is Centos 7.6 and the version of Vertica is 9.3.1.
Someone can help me?
Thanks for all,
Marcos Armas.
