我正在使用 Solr 7.4 和 Hadoop 2.7.5。我有一个想要备份和恢复的现有集合。我能够毫无问题地完成备份，但现在我想测试恢复 API。我在暂存环境中执行所有这些作为概念证明，因为我必须将我们的生产索引恢复到新服务器上。

我遇到的主要问题是我不知道我是否正确使用了恢复 API。这就是我所说的：http://localhost:8983/solr/MyNewTestCollection/replication?command=restore 我需要在 API 中使用“repository”和“location”参数吗？我的理解是没有，因为我的 solr.xml 文件说明了如何使用 HDFS 进行备份/恢复。

在我的 solr.xml 我有：

<backup>
  <repository name="hdfs" class="org.apache.solr.core.backup.repository.HdfsBackupRepository" default="false">
    <str name="location">${solr.hdfs.default.backup.path}</str>
    <str name="solr.hdfs.home">${solr.hdfs.home:hdfs://XXX.XX.XX.XX:8020/user/solr}</str>
    <str name="solr.hdfs.confdir">${solr.hdfs.confdir:/etc/hadoop/conf}</str>
  </repository>
</backup>

此外，以下是我通过调用 API 得到的输出：

<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
<title>Error 500 Server Error</title>
</head>

如果有人需要此信息，以下是我采取的步骤。

  1. 正如我最初提到的那样，我将块添加到我的 solr.xml 文件中
  2. 我使用 Solr Admin UI 创建了新集合
  3. 创建集合时，我通过在下拉菜单中选择它来提供用于新集合的现有配置集
  4. 我将使用 Solr 备份 API 创建的快照上传到我在 HDFS 中设置的默认备份路径
  5. 我调用 Solr 恢复 API 如下： http://localhost:8983/solr/MyNewTestCollection/replication?command=restore&repository=hdfs&location=PathToBackupInHdfs&name=SnapshotName
