Fail when add cluster

[#1]

After I deleted the old cluster and then recreated a new one. I had a new error never got before at the Command Details step. I don't know exactly what is the reason, can someone help me fix this issue?

here is the Error Log of Cloudera scm server:

2024-07-31 15:56:09,184 ERROR CommandPusher-1:com.cloudera.cmf.model.DbCommand: Command 1546343795(Format) has completed. finalstate:FINISHED, success:false, msg:Failed to format NameNode.

Hello @Tung

@Tung if you are configuring a new cluster then the NN data directory should be empty, otherwise, NN formatting will fail. Please check if that's the issue else please paste the full error stack

Thank you, I resolved it after clear all /dfs/nn and /dfs/dn at all nodes, and recreated all databases.
