Homebrew-core: Elasticsearch 5.0.2 not starting

Heyo brewers.

Brew services list is reporting that Elasticsearch has started but it's not (connection refused from curl -X GET http://localhost:9200). The errors suggest that there's some strange path. But, the plugins path exists (/usr/local/Cellar/elasticsearch/5.0.2/libexec/plugins) and the dir is empty. Thoughts?

Errors extracted from stdout:

ignoring unsupported logging configuration file [/usr/local/Cellar/elasticsearch/5.0.2/libexec/config/logging.yml], logging is configured via [/usr/local/Cellar/elasticsearch/5.0.2/libexec/config/log4j2.properties

uncaught exception in thread [main]
org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: unknown setting [path.plugins] please check that any required plugins are installed, or check the breaking changes documentation for removed settings

Found issue. Blow away previous config file, per:
https://github.com/elastic/elasticsearch/issues/21162

rm /usr/local/etc/elasticsearch/elasticsearch.yml

Then all is fine!
