我的es在使用此配置的logstash工作正常：
es config file：
cluster.name: rb_dev
node.data: true
node.name: test_01_dev
path.data: /data/elasticsearch
network.host: 0.0.0.0
network.publish_host: 255.255.255.255
http.port: 9200
然后我需要运行一些groovy脚本，所以我先停止了logstash，然后我停止了elasticsearch，然后将这些行添加到配置文件中：
script.engine.groovy.inline.update: on
script.engine.groovy.inline.search: on
script.engine.groovy.inline.aggs: on
然后我开始弹性搜索并检查日志文件，这个错误开始了......
日志文件显示以下错误：

现在，即使我评论了这个变化，我仍然会收到错误。 我尝试添加：
discovery.zen.minimum_master_nodes: 1
...但错误仍然存在。
