Hi,
You should better use the find module instead of shell module and ls.
As said, yum seem to be a group... To use hostvars special variable you
need to use host and not group...
Something like this will work :
msg: "{{ hostvars['YUM01']['some_value'] }}"
But instead of asking to remove your error, perhaps you could explain
what you want to do...
Regards,
JYL
