Elasticsearch settings not applied

I'm trying to change the logging level of elasticsearch like this:

PUT /_cluster/settings
{
    "transient" : {
        "logger.discovery" : "DEBUG"
    }
}

I performed the PUT, and got a response:

{
  "acknowledged": true,
  "persistent": {},
  "transient": {
    "logger": {
      "discovery": "DEBUG"
    }
  }
}

I'm expecting the log-level to change immediately to DEBUG, but it's still on INFO. Any ideas, what the problem is, or how to debug this problem?

For Elasticserach 5 you need a different command (with full package name in it):

PUT /_cluster/settings
{"persistent": {"logger.org.elasticsearch.discovery":"DEBUG"}}

Relevant documentation: https://www.elastic.co/guide/en/elasticsearch/reference/5.1/misc-cluster.html#cluster-logger

I assume you want to set the root log level and not just discovery to debug:

PUT /_cluster/settings
{
    "transient" : {
        "logger._root" : "DEBUG"
    }
}

You can change the log level in the following file 

/etc/elasticsearch/log4j.properties

In there, you can change the value for the logger you want, or simply set the rootLogger.level to debug. Prepare for an avalanche of logs if you do so.

You need to restart the service for this to be effective.
