在Solr Cloud中,分布式集合中的QueryElevationComponent是必需的吗?(In Solr Cloud, is QueryElevationComponent mandatory in distributed collection?)

我有分布在多个solr云节点上的集合。 要在模式中禁用uniqueKey,我还在solrconfig.xml中禁用QueryElevationComponent。

<!--
  <searchComponent name="elevator" class="solr.QueryElevationComponent" >
    <str name="queryFieldType">string</str>
    <str name="config-file">elevate.xml</str>
  </searchComponent>
-->

配置在未分配的集合中工作正常(1个分片,1个rf)。 但是如果分片数* rf大于1,则会出现问题。 当我执行查询到分布式集合时,比solr抛出异常。

org.apache.solr.handler.component.QueryComponent.createMainQuery(QueryComponent.java:852)中的org.apache.solr.handler.component.QueryComponent.regularDistributedProcess(QueryComponent.java:721)中的java.lang.NullPointerException。位于org.apache.solr.handler.RequestHandlerBase的org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:345)中的apache.solr.handler.component.QueryComponent.distributedProcess(QueryComponent.java:674)。的handleRequest(RequestHandlerBase.java:154)

Solr并没有抱怨索引。 只有查询才有问题。


I have collection that is distributed over multiple solr cloud node. To disable uniqueKey in schema, I also disable QueryElevationComponent in solrconfig.xml.

<!--
  <searchComponent name="elevator" class="solr.QueryElevationComponent" >
    <str name="queryFieldType">string</str>
    <str name="config-file">elevate.xml</str>
  </searchComponent>
-->

Configuration works fine in undistributed collection (1 shard, 1 rf). But if number of shards*rf are greater than 1, problem occures. When I execute query to distributed collection, than solr throws below exception.

java.lang.NullPointerException at org.apache.solr.handler.component.QueryComponent.createMainQuery(QueryComponent.java:852) at org.apache.solr.handler.component.QueryComponent.regularDistributedProcess(QueryComponent.java:721) at org.apache.solr.handler.component.QueryComponent.distributedProcess(QueryComponent.java:674) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:345) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:154)

Solr does not complain against indexing. Only querying is problem.

最满意答案

答案是在webapp / WEB-INF中创建具有以下内容的glassfish-web.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">
<glassfish-web-app error-url="">
    <property name="alternatedocroot_1" value="from=/upload/* dir=C:/opt/oracle/webapps/asd"/>
</glassfish-web-app>

The answer is creating glassfish-web.xml in webapp/WEB-INF with following content

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">
<glassfish-web-app error-url="">
    <property name="alternatedocroot_1" value="from=/upload/* dir=C:/opt/oracle/webapps/asd"/>
</glassfish-web-app>
