Hi this is our initial deployment creating an elastic search instance and installing via Puppet we are seeing this error.

I found out a bit more information. This appears to be an issue with major and minor versioning. I ran a puppet apply in trace mode and got this stack trace.

@styriver when the catalog ran (and when you actually instantiate your elastic_stack::search class, is the Elasticsearch package actually being installed/set to present? It looks like the version logic in the code is trying to compare versions with :absent at some point.

Hi

Thank you for the response. I figured it out this morning. When I am building this string I am appending the .rpm
$rpm_pkg_name = "${pkg_prefix}-${pkg_version}.rpm"

This was causing the versions to not be inferred correctly. The code is using regex to get the package versions. Once I removed the .rpm from that string and just addedthe .rpm to the end of the package url it worked.

Thanks for your time on this issue.
