NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{QVFHsEVaRHiYIb

使用java api和elastic search进行交互时，进行到如下代码编写:

elasticsearch:
  cluster:
    name: elasticsearch
  host: 127.0.0.1
  port: 9200
 

SearchRequestBuilder searchRequestBuilder = this.esClient
        .prepareSearch(INDEX)
        .setTypes(TYPE)
        .setQuery(boolQueryBuilder)
        .addSort(MovieSearch.RELEASE, SortOrder.DESC)
        .setFrom(0)
        .setSize(10)
        .setFetchSource(includes, null);

抛出错误 :NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{erAdMJ4wTNGxixzYoTGhCw}{127.0.0.1}{127.0.0.1:9200}]]。

解决方案:

1、elastic search配置错误，es与java交互的默认端口号是9300，与http交互的端口号是9200，两者不要搞错了，我的就是这种情况，把application.yml配置文件里的es配置的port改为9300即可;

2、如果上述第一步骤还不起作用，则修改下es配置文件elasticsearch.yml中:

network.host: 127.0.0.1
cluster.name: elasticsearch

network.host即部署elastic search服务的机器ip，cluster.name可自定义，但是要和你项目中的elasticsearch.cluster.name值对应。上述两个方式可以顺利解决错误NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{erAdMJ4wTNGxixzYoTGhCw}{127.0.0.1}{127.0.0.1:9200}]]。
