Hello everybody,  
I'm trying to set up multiple Elasticsearch nodes in one installation.  
For the moment it is a test so I have no performance problems (but any advice is welcome).  
Based on some readings on the net I tried like this:

1. I renamed Elasticsearch.yml to Elasticsearch.yml.bck,
2. I created two Elasticsearch-1.yml and Elasticsearch-2.yml with the following content (change "1" with "2" on all parameters to obtain the second node):

```auto
node.name: node-1
path.data: /var/lib/elasticsearch-1
path.logs: /var/log/elasticsearch-1
http.port: 9201
transport.port: 9301
network.bind_host: 0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"

```

1. I created the new folders by copying from /var/lib/Elasticsearch and from /var/log/Elasticsearch:  
/var/lib/Elasticsearch-1  
/var/lib/Elasticsearch-2  
/var/log/Elasticsearch-1  
/var/log/Elasticsearch-1

When I start the service I get the following error messages from Log4J:

```auto
elasticsearch.service - Elasticsearch
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; disabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Wed 2021-12-15 10:39:41 CET; 4s ago

```

Unfortunately I'm not familiar with Log4J, what can be the problem?

Thanks in advance for any suggestions.
