Question

我们正在使用solr6.2版本，现在正在将其迁移到最新的solr8.2版本。所有我们的测试案例在创建集群时都失败了。我们正在使用MiniSolrCloudCluster创建集群，但是在内部使用了JettySolrRunner类，其中很少使用方法和类。因此，我们收到以下错误：

Java.lang.Exception：启动MiniSolrCloudCluster时出错 在org.apache.solr.cloud.MiniSolrCloudCluster.checkForExceptions（MiniSolrCloudCluster.java:652）在org.apache.solr.cloud.MiniSolrCloudCluster（MiniSolrCloudCluster.java:306）在org.apache.solr.cloud.MiniSolrCloudCluster。（MiniSolrCloudCluster.java:239）在org.apache.solr.cloud.MiniSolrCloudCluster（MiniSolrCloudCluster.java:219）在org.apache.solr.cloud.MiniSolrCloudCluster（MiniSolrCloudCluster.java:146）。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。 禁止显示：java.lang.NoSuchMethodError：org.eclipse.jetty.util.thread.QueuedThreadPool.setReservedThreads（I）V 在org.apache.solr.client.solrj.embedded.JettySolrRunner.init（JettySolrRunner.java:265）在org.apache.solr.client.solrj.embedded.JettySolrRunner。（JettySolrRunner.java:257）在org.apache.solr.client.solrj.embedded.JettySolrRunner。（JettySolrRunner.java:229）在org.apache.solr.client.solrj.embedded.JettySolrRunner（JettySolrRunner.java:216）中在org.apache.solr.cloud.MiniSolrCloudCluster.startJettySolrRunner（MiniSolrCloudCluster.java:465）在org.apache.solr.cloud.MiniSolrCloudCluster.lambda $ new $ 0（MiniSolrCloudCluster.java:300）在java.util.concurrent.FutureTask.run（FutureTask.java:266）在org.apache.solr.common.util.ExecutorUtil $ MDCAwareThreadPoolExecutor.lambda $ execute $ 0（ExecutorUtil.java:209）中在java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1149）在java.util.concurrent.ThreadPoolExecutor $ Worker.run（ThreadPoolExecutor.java:624） ...还有1个

 public MiniSolrCloudCluster cluster() throws Exception {
        JettyConfig jettyConfig = JettyConfig.builder().setContext("/").build();
        return new MiniSolrCloudCluster(3, Paths.get("build/cluster"), jettyConfig);
    }

请建议是否有任何方法可以使用solr-core-8.2.0创建solr集群

您可以尝试像我一样创建solr集群。

import org.apache.solr.client.solrj.SolrServerException;
import org.apache.solr.client.solrj.embedded.JettyConfig;
import org.apache.solr.client.solrj.request.CollectionAdminRequest;
import org.apache.solr.client.solrj.request.ConfigSetAdminRequest.List;
import org.apache.solr.client.solrj.response.CollectionAdminResponse;
import org.apache.solr.client.solrj.response.ConfigSetAdminResponse;
import org.apache.solr.cloud.MiniSolrCloudCluster;

import java.io.File;
import java.io.IOException;
import java.nio.file.Path;

public class MiniSolrCloudClusterUtil {
    private MiniSolrCloudCluster miniSolrCloudCluster;

    public MiniSolrCloudClusterUtil(String fileLoc, int numServers) {
        Path baseDir = (new File(fileLoc)).toPath();
        JettyConfig jettyConfig = JettyConfig.builder().setPort(0).build();

        try {
            this.miniSolrCloudCluster = new MiniSolrCloudCluster(numServers, baseDir, jettyConfig);
        } catch (Exception var6) {
            throw new IllegalArgumentException("MiniSolrCloudCluster cannot be created. ", var6);
        }
    }

    public MiniSolrCloudCluster getMiniSolrCloudCluster() {
        return this.miniSolrCloudCluster;
    }

    public ConfigSetAdminResponse listConfigSets() {
        try {
            return (new List()).process(this.miniSolrCloudCluster.getSolrClient());
        } catch (IOException | SolrServerException var2) {
            throw new IllegalArgumentException("Unable to pull config set", var2);
        }
    }

    public CollectionAdminResponse getSolrClusterStatus() {
        try {
            return CollectionAdminRequest.getClusterStatus().process(this.miniSolrCloudCluster.getSolrClient());
        } catch (IOException | SolrServerException var2) {
            throw new IllegalArgumentException("Unable to pull config set", var2);
        }
    }
}

使用MiniSolrCloudCluster创建群集时出错
