Summary: ranger-kafka-plugin find resource bug
Key: RANGER-2461
URL: https://issues.apache.org/jira/browse/RANGER-2461
Project: Ranger
Issue Type: Bug
Components: plugins
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:
