Configurations setting does not restric delete of all indices

Elastic Stack Elasticsearch
1

ES version: 2.2.0
Java 1.8.0_74-b02
OS: 3.16.0-60-lowlatency (Ubuntu 14.04)

Expected behavior, it should not delete all indices when the configuration setting action.disable_delete_all_indices is set to true.

Configuration setting in file elasticsearch.yml
action.disable_delete_all_indices: true.

root@es-thr-chef-m01:/# curl -XPUT 'http://localhost:9200/customer?pretty'
{
"acknowledged" : true
}
root@es-thr-chef-m01:/# curl -XDELETE 'http://localhost:9200/*?pretty'
{
"acknowledged" : true
}
root@es-thr-chef-m01:/# curl 'http://localhost:9200/_cat/indices?v'
health status index pri rep docs.count docs.deleted store.size pri.store.size

(All indexes deleted)

Did you restart Elasticsearch after applying the setting?

yes.

Repeated again:
root@es-thr-chef-m01:/# service elasticsearch stop

  • Stopping Elasticsearch Server [ OK ]
    root@es-thr-chef-m01:/# service elasticsearch start
  • Starting Elasticsearch Server [ OK ]
