Issue
I am currently using chef to install the RPM JDK package but the problem is that it does it every single time even if the package is already downloaded and installed. I tried finding an option for checking before installing but there wasn't any. Is there a way to get around this such that I can skip packages that are already installed? Debian's package management skips already installed packages by default, but RPM package manager doesn't seem to do that.

#Remove old environment then notify new environment to be created

end
Solution
I know this is old, but I believe you want:
remote_file "your-remote-file" do
...
not_if "rpm -qa | grep -qx 'your-package'"
end
