问题标签 [elassandra]

我试图将我的 Elassandra 连接到 Kibana 7x，但遇到了一些兼容性问题，似乎 Elassandra 使用 Elasticsearch 6.2.3 而我试图连接到 Kibana 7。需要帮助将 elasticsearch 服务升级到 7x 或将 kibana 7x 连接到 elasticsearch 6x。

通过浏览文档，我尝试使用 cassandra -e 命令运行 elassandra，但它正在工作并抛出无效参数：空值错误

我相信命令应该不同，你能分享一下命令吗？谢谢

I recently started working with an Elassandra cluster with two data centers which have been configured using NetworkTopologyStrategy.

Cluster details : Elassandra 6.2.3.15 = Elasticsearch 6.2.3 + Cassandra 3.11.4

schema info
CREATE KEYSPACE my_keyspace WITH replication = {'class': 'NetworkTopologyStrategy', 'DC1': '3', 'DC2': '3'} AND durable_writes = true;

The DC2 is kind of a Disaster Recovery site and in an ideal world, we should be able to use only that in case of a disaster.

1. With the very limited knowledge I have, I strongly suspect that we need to modify the rack configuration to have a 'proper' D/R cluster (So that data in DC1 gets replicated in DC2) or am I getting this wrong? If so, is there a standard guideline to follow?
2. When there are multiple DCs, does Cassandra automatically replicate this regardless of rack configurations? (Are racks kind of additional fail proof?)
3. DC2 has more data than DC1. Is this purely related to hash function?
4. Is there any other things that can be rectified in this cluster?

Many thanks!

我正在尝试在 Docker 映像中使用 elassandra（即 elasticsearch + cassandra），所以我是它的初学者。在这种情况下，我的问题可能是初学者级别，抱歉:)

我已经启动了那个 docker 镜像，我可以插入数据并搜索它，但我不知道如何创建一个新的集群。根据此文档，我需要在我的图像中找到 elasticsearch.yml 文件，但我无法通过 docker cli 终端找到它：https ://elassandra.readthedocs.io/en/latest/configuration.html

到目前为止，我尝试使用“find .elasticsearch.yml”命令，但在整个图像目录中没有这样的文件。

感谢您的关注。祝你今天过得愉快！
