Continuing the discussion from [Ansible Role for Elasticsearch now available!](https://discuss.elastic.co/t/ansible-role-for-elasticsearch-now-available/39848): I have many clusters running ES v1.x which were deployed by my own Ansible playbooks, which originated in the old Traackr version ([https://github.com/Traackr/ansible-elasticsearch](https://github.com/Traackr/ansible-elasticsearch)) I have a new v2.2 cluster (testing for migration) and used the new 'official' role from [https://github.com/elastic/ansible-elasticsearch](https://github.com/elastic/ansible-elasticsearch) Everything is on Ubuntu 14.04 (trusty) at the moment. During testing I was surprised to discover that the elasticsearch role `java.yml` task installed `openjdk-7-jre-headless` since the docs say to use Oracle JDK 8: > ...as of this writing, it is recommended that you use the Oracle JDK version 1.8.0\_73 [https://www.elastic.co/guide/en/elasticsearch/reference/current/\_installation.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html) (That's in `vars/Debian.yml`, the alternate `vars/Redhat.yml` specifies `java-1.8.0-openjdk.x86_64`) I'm wondering what the motivation is in the Ansible for installing versions contrary to in-house recommendations. 😕 Generally wondering, is this simply a question of what can be found in the Debian/Ubuntu repos? But specifically wondering, should I modify that section to install Oracle 8 (I'm thinking yes). I am concerned that there are Java args or environment settings hard-coded elsewhere in the Ansible role which presume OpenJDK... 😕 Will dig, but wondering! best regards, aaron ---

It's a recommendation, not a requirement. Plus there is no openjdk 8 in base 14.04. ---

Certainly... ...but I still ask, why not ship an installer that uses the recommended (Oracle) version? ---

Because not everyone is willing to agree to the Oracle license, so we don't force it on people. This behaviour aligns with our other automation packages too. ---
