No live SolrServers available to handle this request , no servers hosting shard 当某一片索引对应的结点全部宕了以后,会报这个异常. "error": { "msg": "no servers hosting shard: ", "code": 503 } 需要在请求上加上: params.setParam("shards.tolerant…

原因: haproxy 对server检测时是对默认页面进行检测,如果没有默认错误,则直接报503错误,不会转发到相应的server上去. 解决方法: 添加 option httpchk 检测页面位置如:/login/login.jsp.…

SolrDispatchFilter的作用 This filter looks at the incoming URL maps them to handlers defined in solrconfig.xml 将请求的url映射到solrconfig.xml定义的handler上. 该过滤器的doFilter方法主题: HttpSolrCall call = getHttpSolrCall((HttpServletRequest) request, (HttpServletResponse…

CloudSolrClient是solrj提供的客户端与solrCloud交互的类.该类的实例与zookeeper进行通信来确定solrCloud collections中的solr endpoint,然后使用LBHttpSolrClient发送请求. CloudSolrClient查询简单代码: import java.io.IOException; import org.apache.solr.client.solrj.SolrQuery; import org.apache.solr.cl…

As you know, I've been playing with Solr lately, trying to see how feasible it would be to customize it for our needs. We have been a Lucene shop for a while, and we've built our own search framework around it, which has served us well so far. The ra…

用solr做项目已经有一年有余,但都是使用层面,只是利用solr现有机制,修改参数,然后监控调优,从没有对solr进行源码级别的研究.但是,最近手头的一个项目,让我感觉必须把solrn内部原理和扩展机制弄熟,才能把这个项目做好.今天分享的就是:Solr是如何启动并且初始化的.大家知道,部署solr时,分两部分:一.solr的配置文件.二.solr相关的程序.插件.依赖lucene相关的jar包.日志方面的jar.因此,在研究solr也可以顺着这个思路:加载配置文件.初始化各个core.初始化各个…
