Read the document carefully. You changed the application.yml incorrectly.

i just config the yml storage nodes

storage:
elasticsearch:
clusterName: CollectorDBCluster

elk.yml config is
cluster.name: CollectorDBCluster

run skywalking startup.bat

error is :

Please read the document, we have indicated how to set up ElasticSearch as storage. Also, the document has guided you about how to do a quick start.

仔细阅读文档。你改错了application.yml。

我只是配置yml存储节点

storage：
elasticsearch：
clusterName：CollectorDBCluster

elk.yml config是
cluster.name：CollectorDBCluster

运行skywalking startup.bat

错误是：

Cluster module exist 2 providers, is this problem handled?

This is also another example of not reading document.
