@@ -14,6 +14,15 @@ The goal of this fabric script is to setup a test cluster on baremetal leveragin
     - nodes data bag
 - From the utils directory (or specifying that fabfile) start the install script
   - `fab cluster.setup -H host1,host2,host3`
-- Setup the Vertica database schema
+- create kafka topics - kafka::create_topics recipe can be run on 1 machine
-- Setup the mysql database schema
+- Setup the Vertica database schema - the vertica::create_db recipe and scripts can be used for reference but won't work for a cluster
-- Restart any services which require vertica or mysql
+  - The problems with the script are:
+    - The create_db command needs all ips specified for the -s arg, they are comma seperated
+    - The symbolic linking of ssl cert/key needs to be done on each node
+    - The restart policy should be set to ksafe rather than always
+- Setup the mysql database schema - the mini-mon::mysql_schema tecipe can be run on 1 machine
+- Restart any services which require vertica, mysql or kafka
+
+
+## Optional Configuration
+- Add in the Vertica Console to one of the machines. This can be done with vertica::console recipe
