apache - [schema.xml] fieldType "pint": Error loading class 'solr.IntField' 的 SolrException 插件初始化失败

Question

我收到此错误

collection1: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not load conf for core collection1: Plugin init failure for [schema.xml] fieldType "pint": Error loading class 'solr.IntField'.

当我尝试将集合 1(solr 4.5)模式导入到 solr 5.1 时。

我只从运行 solr 4.5 的不同机器复制集合 1 并粘贴在这里/solr/server/solr/collection1 运行 solr 5.1 并重新启动 solr。抱歉，我是初学者，对 solr 知之甚少，只需遵循一些教程即可。

Answer 1

我认为在您早期版本的 schema.xml 中，您的字段类型为 pint
现在在当前版本中它不受支持，因为我在 schema.xml 中看不到 fieldType(在我下载 Solr.5.1.0 时的默认设置中)。
更换/删除它，错误将得到纠正。
这个 fieldType 在早期版本中就有(我用的是 3.4)

<fieldType name="pint" class="solr.IntField" omitNorms="true"/>

在当前的 5.1.0 中，我看不到此字段类型。
或者
您应该更换 solr.IntField与 solr.TrieIntField
