如何修复此代码异常错误elasticsearch

Question

我目前正在使用elasticsearch,logstash和kibana.

我得到一个我无法通过的例外.

首先,这是我在浏览器中输入ip:9200/_cluster/health时得到的内容..

{
 "cluster_name":"mr-cluster",
 "status":"yellow",
 "timed_out":false,
 "number_of_nodes":1,
 "number_of_data_nodes":1,
 "active_primary_shards":5,
 "active_shards":5,
 "relocating_shards":0,
 "initializing_shards":0,
 "unassigned_shards":5
}

以下是kibana在尝试请求弹性搜索时获得的内容

Remote Address:ip:9200
Request ip:9200/_all/_search
Request Method:POST
Status Code:200 OK

到现在为止似乎没问题..

这是我的logstash配置文件:

input {
gelf {
    port => "5000"
}
udp {
    port => "5001"
}
}

output {
file {
    path => "/home/g/stdout.log"
}
elasticsearch {
    cluster => "mr-cluster"
    codec => "json"
}
}

当我只使用一个文件作为输出时它非常简单,它可以很好地工作,logstash工作.问题是,当我想使用elasticsearch作为输出时,没有任何东西可以工作(事件文件输出),我从elasticsearch获得此异常.我一直在谷歌搜索几个小时,但没有找到解决方案.

这是一个例外:

谢谢你的帮助!

配置 Elasticsearch 的方式（仅使用集群名称）会触发集群的多播发现。您可以尝试直接在集群中进行配置，看看是否有效：

elasticsearch {
    host=>"ip_here"
    port=>9200
    protocol=>http
}

此外，您的集群输出表示您的集群处于“黄色”状态，因此您可能想弄清楚那里发生了什么 - 您希望它处于“绿色”状态。
