Solr 6.6.6 集合还原导致单节点问题

Question

我有 2 个节点 SolrCloud 设置。 版本是 6.6.6。 我从其他有 4 个收集碎片的实例中获取了 Solr 备份。

我已经使用以下命令收回工作正常

http://10.11.31.11:8983/solr/admin/collections?action=BACKUP&name=hms&collection=collection1&location=/tmp/solr_backup&async=1001

在此之后，我将备份复制到 Solr Cloud 的一个节点并执行以下命令进行恢复。

http://10.11.31.12:8983/solr/admin/collections?action=RESTORE&name=hms&location=/home/hduser/Documents/search/data&collection=newCollection&maxShardsPerNode=4&replicationFactor=2&autoAddReplicas=true

执行上述命令时出现以下异常

然后我将备份数据复制到第二个节点，其路径也与第一个节点完全相同，并重新执行了恢复命令。 工作很成功。

这是否意味着对于每个备份，都需要在 Solr 的所有节点上以完全相同的路径复制备份，或者这是一个错误？

我期待 Solr 应该允许从单个节点恢复集合，然后它应该自己复制分片？ 不是吗？

Answer 1

您要从中恢复的目录必须在同一路径的所有服务器上可用。 假定该路径是服务器上公共位置中可用的网络共享。

地点

共享驱动器上要读取的还原命令的位置。

从上面给出的文档中的示例：

..&name=myBackupName&location=/path/to/my/shared/drive&...
