2. SolrCloud Node VM prerequisites
As I mentioned on the Home page, it was decided to go "not really best practice" way and deploy Zookeeper Nodes on the same Server with SolrCloud nodes.
I used Windows Server 2016 Datacenter image from Azure Marketplace as a base for my VMs.
Both things are running as Windows Services powered by NSSM.
On each VM should be JRE 1.8 installed.
Note: I experience some issues when using JRE 10 for running Solr, so that I decided to go strictly with JRE 1.8
Note 2: since JRE/JDK is licensed by Oracle, OpenJDK can be used instead, for example this one
Make sure that Java is properly registered in Environment Variables:
To check that, you may open command prompt and try to run following command. If it works, your Java is installed correctly.
java -version
Finally make sure Windows firewall on this VM allows inbound connections for some specific SolrCloud ports. See more information in Ports and Firewalls article in this wiki.
