我正在尝试应用一些集群级别的自动缩放策略，为此我正在尝试创建一个节点集。根据文档，有一些方法可以创建节点集(根据一些规则选择一组节点(：https://lucene.apache.org/solr/guide/8_3/solrcloud-autoscaling-policy-preferences.html#node-选择属性
文档声明我们可以使用sysprop。｛PROPERTY_NAME｝：指定一组节点。sysprop.key表示在节点启动期间以-Dkey=keyValue的形式传递给节点的值。
这是我用来启动节点的命令
bin/solr start -cloud -s example/cloud/node/solr -p 8987 -Dkey=noderef -z localhost:9983
然而，在上面的命令之后，我得到了以下错误
javax.servlet.UnavailableException: Error processing the request. CoreContainer is either not initialized or shutting down.

有人能指出我在这里做什么吗。基本上，我想将一组节点标记为"pullnodes"，将另一组标记为"tlognodes"，这样我就可以将不同的调整集群策略应用于相同的
出现语法问题，需要用引号传递键值，如
bin/solr start -cloud -s example/cloud/node/solr -p 8987 "-Dkey=noderef" -z localhost:9983
此外，它似乎在本地云模式下不起作用，在单独的机器上用节点尝试了上面的命令，它起到了的作用
