Hello,  
I have been trying to setup causal cluster with the help of documentation using 3 VMs as core nodes. They are not forming a cluster and i see below warning in the logs for the settings required to form a cluster.  
user@neo4j01:~/neo4j-community-4.3.10/logs$ tail -f neo4j.log  
WARN Unrecognized setting. No declared setting with name: causal\_clustering.discovery\_listen\_address  
WARN Unrecognized setting. No declared setting with name: causal\_clustering.raft\_listen\_address  
WARN Unrecognized setting. No declared setting with name: causal\_clustering.discovery\_advertised\_address

I hope there is no external plugin required to setup a cluster.

Appreciate any suggestions here.

Thanks

Hi All

any help n this please. Below are the settings being used in neo4j.conf(changing ips).  
I am trying to form a cluster using neo4j community version 4.3.10, is it possible to create cluster using community version or it is only with enterprise version ?

@ahemad_shaik

per [Clustering - Operations Manual](https://neo4j.com/docs/operations-manual/current/clustering/)

it reports

```auto
Clustering [Enterprise Edition]

```

and thus a enterprise only feature.

Further [Introduction - Operations Manual](https://neo4j.com/docs/operations-manual/current/introduction/#edition-details) provides a list of functionality per edition and Table 6.2 states

```auto
6.2. Performance and scalability
Table 2. Performance and scalability features
Feature Community Edition	Enterprise Edition
Causal Clustering for global scale applications X V

```
