Hi,

I am running integration tests using the REST API `esplugin` tooling and I want to make sure the [`do:`](https://github.com/elastic/elasticsearch/tree/v6.4.2/rest-api-spec/src/main/resources/rest-api-spec/test#do) operators are executed against specific node only.

I am aware of the `node-selector` filter but I do not know how I can assign different attributes to individual test nodes so that I can filter them using this attribute. Is there any way how I can enhance default `elasticsearch.yml` config for test nodes and add different attributes to individual nodes? Or is there any other way how I can do it?

I use

```auto
integTestCluster {
    numNodes = 2 //or more
}

```

in `build.gradle` to tell `esplugin` to start cluster with more than a single node.

One alternative would be if I could address individual nodes using node name (`node-0`, `node-1`, ...) but that does not seem to be supported atm.

Regards,  
Lukáš

Seems to me that if I find out how to propagate distinct attributes here: [https://github.com/elastic/elasticsearch/blob/master/buildSrc/src/main/groovy/org/elasticsearch/gradle/test/ClusterFormationTasks.groovy#L344](https://github.com/elastic/elasticsearch/blob/master/buildSrc/src/main/groovy/org/elasticsearch/gradle/test/ClusterFormationTasks.groovy#L344)

for example `node.attr.label=foo` for the first node and `node.attr.label=bar` for the second node then I should be able to use:

```auto
- do:
    node_selector:
      attribute:
        label: foo

```

to send request to node having label=foo.

Alternative is to find out how to pass arguments via System property to Node here: [https://github.com/elastic/elasticsearch/blob/master/buildSrc/src/main/groovy/org/elasticsearch/gradle/test/NodeInfo.groovy#L194](https://github.com/elastic/elasticsearch/blob/master/buildSrc/src/main/groovy/org/elasticsearch/gradle/test/NodeInfo.groovy#L194)  
Arguments like `tests.es.node.attr.label=foo`

Anyone tried this before?

Thanks,  
Lukáš
