How to fix UBA No HDFS datanodes found?

Hi, I just installed UBA on RHEL 8.4 and started it first time. However it failed to start. Then I tried to stop-all and start-all to find which service is wrong. It looks like HDBS data node is not failed, but I don't know to fix it individually. Can anyone give me a hand?
