我们正在 Docker 中运行 JanusGraph 以及 Cassandra 和 Elasticsearch 的两个集群。

networks:
  jce-network:

volumes:

Dockerfile如下

FROM docker.io/janusgraph/janusgraph:latest

WORKDIR /opt/janusgraph
USER root

# Copy configuration files
COPY janusgraph-server.yaml /opt/janusgraph/conf/janusgraph-server.yaml
COPY empty-sample.groovy /opt/janusgraph/scripts/empty-sample.groovy
COPY janusgraph-keyspace-one.properties /opt/janusgraph/conf/janusgraph-keyspace-one.properties
COPY janusgraph-keyspace-two.properties /opt/janusgraph/conf/janusgraph-keyspace-two.properties

# Set ownership for the entire conf directory in one step
# RUN chown -R janusgraph:janusgraph /opt/janusgraph/conf

USER janusgraph

WORKDIR /opt/janusgraph

我们有两个名为 

keyspace_one
和 
keyspace_two
的键空间，我们正在尝试按照命令拍摄键空间 
keyspace_one
的快照。

docker exec -it jce-cassandra-1 nodetool snapshot keyspace_one

我们已成功创建快照文件夹，一切正常。现在，我们正在尝试将备份的快照恢复到

keyspace_two
。为此，我们将快照数据复制到文档中所述的 
keyspace_two
文件夹中。接下来，我们执行刷新键空间的命令。

nodetool refresh keyspace_two edgestore

我们遇到以下错误：

root@cec647038c56:/var/lib/cassandra/data/keyspace_two# nodetool refresh keyspace_two edgestore

是否有我们可能忽略的配置或命令？

docker elasticsearch cassandra janusgraph

只是一个想法，但这可能仅在目标键空间名称与源相同时才有效。

在快照文件的目录中，查看生成的

schema.cql
文件。尝试将该文件中对 
keyspace_1
的所有引用设置为 
keyspace_2
，然后再次运行刷新。
