我正在尝试将数据从Kafka传递到elasticsearch，然后传递到kibana。我使用Kafka河插件在这篇文章中提到link:elasticsearch-river-kafka plugin
在启动kafka zookeeper、服务器和生产者之后，我将数据作为{“test”：“one”}
然后开始elasticsearch。我在Kafka中遇到了以下错误：

[2016-02-04 00:05:00,094] ERROR Closing socket for /192.168.1.9 because of error (kafka.network.Processor)

在elasticsearch中，出现以下错误：

org.codehaus.jackson.JsonParseException: Unexpected character ('S' (code 83)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')

另外，我在elasticsearch日志中看到： [2016-02-04 00:14:31,340][WARN ][river.routing ] [ISAAC] no river _meta document found after 5 attempts 知道我做错了什么吗？请帮忙。谢谢。
