在datastax升级4.8.8到5.0.2期间添加新的数据中心 [英] add new datacenter during datastax upgrade 4.8.8 to 5.0.2
问题描述
我有多个数据中心。其中之一是Cassandra，另一个是Solr数据中心。我已经开始升级过程。由于 upgradesstables命令已进行了4天，因此仍在升级1个节点。
I have multiple datacenters. One of them is Cassandra other one is Solr datacenter. I already started upgrading process. Still 1 node is being upgrading since "upgradesstables" command have been taking for 4 days.
我想添加新的cassandra数据中心，我没有时间等待升级过程完成。正在进行升级过程时，是否可以添加5.0.2版的新Cassandra数据中心。
I want to add new cassandra datacenter and i dont have time to wait upgrading process is done. Can i add new cassandra datacenter with version 5.0.2 while there is upgrading process is going on.
推荐答案
尽管您可以运行集群处于部分升级状态，它是过渡状态，而不是您希望集群持续任何时间的情况。在集群处于部分升级状态时，应避免执行某些操作，并且在此状态下集群还会显示架构分歧。
Although you can run a cluster in a partially upgraded state, it is a transient state and not a situation you'd want your cluster to be in for any length of time. There's some operations you should avoid while the cluster is in a partially upgraded state and also your cluster will show a schema disagreement while in this state.
我会说最好不要将该新DC添加到混合中。请在此处查看升级限制：
I would say its best to not add that new DC into the mix. Please see the upgrade limitations here:
