[GitHub] [iotdb] tarungoswami opened a new issue, #6894: IoTDB Cluster Error

URL: https://github.com/apache/iotdb/issues/6894
Hello Team,
We are trying to run cluster using 2 servers say n1,n2(with 1C1D on each). With normal configuration the cluster is performing correctly.
Then to test data availability I stopped one of the datanode (say datanode of n2), after this when I ran some query to fetch the data,
it throws error like can't connect to datanode on n2. I tried to increase the replication factor as well, but when I changed the
replication factor to 2 then I am having this issue.

因为默认的data_region_consensus_protocol_class 配置是standalone模式，所以副本只能设置为1，需改data_region_consensus_protocol_class 为其它模式，就可以设置多副本
