Hi All, As it currently sits, once METRON-1758 <https://github.com/apache/metron/pull/1179> is merged into the code base, Ansible 2.4 or later will be required to use any of the Metron ansible playbooks. This is in contrast to the prior version requirements outlined in Metron documentation which specifically point to 188.8.131.52 and 184.108.40.206 as supported/recommended Ansible versions. If you install Ansible 2.5.0 exactly you should not experience any issues spinning up pre- and post- merge versions of Metron.
I am broadcasting this to both the user and dev communities in advance of any changes to provide an opportunity to voice any concerns. Thanks, Jon -- Jon
