difference between Ambari version1.7.1 and version2.1.1

[#1]

In Ambari 1.7.1 first installation, I can choose to install "Ranger",however it is opposite in Ambari 2.1.1, I can not choose "Ranger" to install. Therefore what`s the reason about these difference? What should I do if I want to install "Ranger" component in Ambari 2.1.1 first installation.

thanks

I found in "ambari-web/app/models/stack_service.js" that we could comment out the "doNotShowAndInstall" function in order to show up Ranger or Ranger KMS in first installation.

the reason is that we want to control the order of install, specifically, we want to make sure mysql database is up, running and accessible so that Ranger would result in successful install. It is by design hidden. @Benson Shih
