无法使用solr API在Solr 8.9.0中创建Solr核心

Question

我已经按照https://gist.github.com/fschiettecatte/836d13be0c95f1fd159e45d3af861952中提到的过程创建了Solr war文件，因为我希望通过我的特定版本的jetty服务器将Solr作为独立应用程序运行。

在创建war文件之后，我通过jetty成功地启动了solr

运行以下命令：

$ java -Djetty.home=/var/solr -Djetty.base=/var/solr
-Dsolr.solr.home=/var/solr/solr -Dsolr.log.dir=/var/solr/solr
-Dbootstrap_confdir=/var/solr/solr/conf -Dcollection.configName=conf
-DzkRun -Djava.util.logging.config.file=/var/solr/solr/solr-log.properties
-jar /var/solr/start.jar

我的solr运行得很好，我运行了几个命令来验证：

$ curl "http://0.0.0.0:8983/solr/admin/collections?action=clusterstatus&wt=xml“

<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader">
  <int name="status">0</int>
  <int name="QTime">19</int>
</lst>
<lst name="cluster">
  <lst name="collections"/>
  <arr name="live_nodes">
    <str>192.168.1.2:8983_solr</str>
  </arr>
</lst>
</response>

当我尝试创建内核时，它失败了，错误如下，之前

运行此命令，我在solr主目录“/var/solr/solr/a10”下创建了名为“cores”的文件夹。

$ curl "http://0.0.0.0:8983/solr/admin/cores?action=CREATE&name=a10&instanceDir=cores/a10&shard=shard10&collection=conf1&coreNodeName=a10&wt=xml“

    <?xml version="1.0" encoding="UTF-8"?>
<response>

 <int name="QTime">10067</int>

 <int name="code">400</int>
</lst>
</response>

由于jetty控制台中的此错误而导致的回溯：

当我在独立模式下启动Solr时，我的问题得到了解决。由于create core命令失败，我在云模式下启动了solr。

Solr接口仅在solr以独立模式启动时使用，在solr以云模式启动时应使用Collection相关接口。
