solr - 无法在 Solr Cloud 上备份和恢复

Question

我正在尝试在 SolrCloud 上测试集合的备份和恢复，但没有任何乐趣（版本 6.6.5）。

我正在做备份：

curl -f "http://127.0.0.1:8080/solr/admin/collections?action=BACKUP&name=$BACKUP_NAME&collection=$TARGET_COLLECTION&location=$BACKUP_LOCATION&wt=json"
{"responseHeader":{"status":0,"QTime":6370},"success":{"solr-2.search-solr.svc.cluster.local:8080_solr":{"responseHeader":{"status":0,"QTime":6143}}}}

但后来我试图运行恢复：

curl -v -f "http://127.0.0.1:8080/solr/admin/collections?action=RESTORE&name=at-uk&collection=at-uk-restore&location=/tmp&wt=json"
* About to connect() to 127.0.0.1 port 8080 (#0)
*   Trying 127.0.0.1...
* Connected to 127.0.0.1 (127.0.0.1) port 8080 (#0)
> GET /solr/admin/collections?action=RESTORE&name=at-uk&collection=at-uk-restore&location=/tmp&wt=json HTTP/1.1
> User-Agent: curl/7.29.0

curl: (22) The requested URL returned error: 500 Server Error

在 solr 日志中：
