Hello, I've installed ambari kafka cluster with such configuration: ambari_version: '2.7.4.0' hdp_version: '3.1.4.0' hdf_version: '3.4.1.1' on CentOS Linux release 7.8.2003 (Core) However, when I'm trying to make some kafka configuration changes - I'm getting error message : Consistency Check Failed The configuration changes could not be validated for consistency due to an unknown error. Your changes have not been saved yet. Would you like to proceed and save the changes?
