运行我的kafka连接器进行elasticsearch时出现异常。我安装了用于elasticsearch的融合kafka连接器，并且将其配置如下：
{
"name": "ElasticsearchSinkConnector2",
"config":{
"connector.class":
"io.confluent.connect.elasticsearch.ElasticsearchSinkConnector",
"topics": "test",
"tasks.max": 1,
"connection.url": "elasticsearch:9200",
"type.name": "log",
"key.ignore":true,
"schema.ignore":true
}
}
但是有一个例外：
