Datastax dsetool Solr create_core TIMEUUID 失败

Question

在DataStax Enterprise Server 4.6.0 上运行 Datastax 工具 从现有表中从头开始生成 Solr

dsetool create_core ks.table generateResources=true distributed=true reindex=true

得到

org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: 

    Type org.apache.cassandra.db.marshal.ReversedType(org.apache.cassandra.db.marshal.TimeUUIDType) 

is not supported with automatic Solr schema generation.

根据http://www.datastax.com/documentation/datastax_enterprise/4.5/datastax_enterprise/srch/srchSolrType.html，Solr 从 4.5 开始支持 uuid 和 timeuuid

建议？

Answer 1

由于 Solr 默认不识别 timeuuid，我们需要手动创建 schema.xml 文件，看起来像这样

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<schema name="autoSolrSchema" version="1.5">
<types>
<fieldType class="org.apache.solr.schema.StrField" name="StrField"/>
<fieldType class="org.apache.solr.schema.UUIDField" name="UUIDField"/>
<fieldType class="org.apache.solr.schema.TextField" name="TextField">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
<fieldType class="org.apache.solr.schema.TrieFloatField" name="TrieFloatField"/>
</types>
<fields>
<field indexed="true" multiValued="false" name="article_url" stored="true" type="StrField"/>
<field indexed="true" multiValued="false" name="articleid" stored="true" type="UUIDField"/>
<field indexed="true" multiValued="false" name="article_title" stored="true" type="StrField"/>
<field indexed="true" multiValued="false" name="image" stored="true" type="StrField"/>
<field indexed="true" multiValued="false" name="history" stored="true" type="UUIDField"/>
</fields>
<uniqueKey>(articleid)</uniqueKey>
</schema> 

并将timeuuid字段定义为UUIDField，见history

然后运行

dsetool create_core kular.articles schema=/home/ubuntu/articles_schema.xml generateResources=true distributed=true reindex=true
