Replica allocation awareness

Elastic Stack Elasticsearch
13

I found 1 hot node still with the allocation setting, can I remove it with an API call or do I need a restart?

The setting is commented out in the elasticsearch.yml

  "settings" : {
    "pidfile" : "/var/run/elasticsearch/elasticsearch.pid",
    "cluster" : {
      "name" : "es-cluster",
      "routing" : {
        "allocation" : {
          "awareness" : {
            "attributes" : "data"
          }
        }
      },
