    Affects Versions: 1.2.0
            Reporter: Konstantin Tsypin


Hi there

Past several days i tried to implement integration apache ranger and ranger-kafka plugin.

*My versions:*

kafka: 2.12_2.2.0

ranger: 1.2.0 , ranger-plugin 1.2.0

*My current problem:*

as far as i understand, kafka cant find the ranger-created audit files that i made with enable-kafka-plugin.sh script (ranger-kafka-audit.xml and ranger-kafka-security.xml). I sold this files everywhere in file system but this class still cant find it and cause fatal error:
