Hi ! I would like to use curator to deleta some indices in my cluster. My cluster is composed of 3 data nodes and 1 client node. My question is: in the config file, which hosts should I write ? only one is enough or all 3 nodes ? Thanks ! ---

Any of the nodes should work, any requests that curator makes will be distributed and redirected within the cluster to get to the right place. ---

on a similar note..i am using config mgmt. to install elasticsearch. I am using curator 4.x which doesn't have --master-only option. How can I make curator run only on one node and not others? ---

It does, but it goes into the configuration file: [https://www.elastic.co/guide/en/elasticsearch/client/curator/current/configfile.html#master\_only](https://www.elastic.co/guide/en/elasticsearch/client/curator/current/configfile.html#master_only) ---

Thank you! Thank you! Thank you! I was about to write a wrapper over curator that will query elastic search and get current master ip to compare current server host ip to make determination. ---
