修改schema.xml后重新加载Solr内核时出错 . 无法实现复制因子1（仅找到0个副本）

目前在Solr模式下与Cassandra合作，并开始在Solr中运行Cassandra .

using dse 4.7
cassandra 2.1.8

./dsetool create_core vin_service_development.vinid_search1 generateResources = true reindex = true

成功创建索引并能够在http://10.14.210.22:8983/solr/#/中的Core Selector Select列表下查看该表

将schema.xml字段类型从“TextField”更改为“StrField”，并希望重新加载对schema.xml文件所做的更改 . 执行以下命令后 .

./dsetool reload_core vin_service_development.vinid_search1 reindex = true solrconfig = solr.xml

solr.xml放在dsetool的相同路径中 .

错误信息：

brsblcdb012:/apps/apg-data.cassandra/bin ./dsetool reload_core vin_service_development.vinid_search1 reindex=true solrconfig=solr.xml

这是在更改xml文件后在Solr中重新加载核心的正确方法吗？

更新：我的一个密钥空间之前使用的是NetworkTopologyStrategy . 将此修复为SimpleStrategy . 现在所有的键空间都在数据中心Solr中具有SimpleStrategy . 执行相同的命令后，出现此错误 .

现在推荐的改变是什么？
