elasticsearch - logstash - 线程 ">output"org.elasticsearch.discovery.MasterNotDiscoveredException : waited for [30s] 中的异常

Question

日志存储对我来说是 100% 的灾难。我在同一台机器上使用 LS 1.4.1 和 ES 1.02。

这是我启动 logstash 索引器的方式:

/usr/local/share/logstash-1.4.1/bin/logstash -f /usr/local/share/logstash.indexer.config
input {
  redis {
    host => "redis.queue.do.development.sf.test.com"
    data_type => "list"
    key => "logstash"
    codec => json
  }
}

output {
        stdout { }
        elasticsearch {
                bind_host => "127.0.0.1"
                port => "9300"
        }
}

我设置的ES:

network.bind_host: 127.0.0.1
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["127.0.0.1:9300"]

哇..这就是我得到的:

/usr/local/share/logstash-1.4.1/bin/logstash -f /usr/local/share/logstash.indexer.config

参见 http://logstash.net/docs/1.4.1/outputs/elasticsearch

VERSION NOTE: Your Elasticsearch cluster must be running Elasticsearch 1.1.1. If you use any other version of Elasticsearch, you should set protocol => http in this plugin.

所以您的问题是 logstash 不支持您在不使用 http 传输的情况下使用的旧 ES 版本。
