Watcher Exception without using Watcher

Elastic Stack Elasticsearch
1

HI, I'm having below exception in elasticsearch, of course, problems goes away once I grant permission to elasticsearch account. But since I'm not using Watcher, and I didn't install the plugin, why is watcher throwing exceptions? and the script folder is empty. Thanks.
I'm using ElasticSearch 2.4, with Marvel installed.

Hey,

the ResourceWatcherService is not a component from watcher, but an Elasticsearch component that watches resources (as in files and directories) to trigger reloading, if on-disk information has changed. This service needs to have read access to the directories it is monitoring. The scripts directory is one of those.

Hope this helps!
