Hi eveyone,
Ambari :- 2.7.4.0
HDP :- 3.1.4.0
I want to know whether postgresql in addition to MYSQL ( I will be using MYSQL in advanced database configuration while setting up Ambari server as my choice ) is needed for Ambari ( 2.7.4 ) installation or not. If it is needed should I install it on both Ambari Server host and also Ambari Agent hosts or only Ambari Server host. On which hosts is it required?
Please help!

You don't really need to mix 2 different databases [Postresql and MySQL]. You can use MySQL or MariaDB free version of MYSQL in the advanced database configuration for you cluster. MySQL has the typical SQL syntax Postgresql is another world !
You don't need to install MySQL on the ambari agent hosts because that will mean if you have 20 nodes you will be running 20 MySQL/MariaDB databases.
Usually, you install the MySQL/MariaDB on the Ambari host and you create apart from Ambari database, hive,oozie, ranger,RangerKMS etc.
If you are deploying using Ambari then the ambari-agents are deployed automatically and configured by Ambari.

Ambari installation requires either MySQL or postgresql. In general, you only need to install MySQL on the Ambari server host.
