좀 전에 kraft라는 디렉토리 안의 <a target="_blank" rel="noopener noreferrer nofollow" href="http://server.properties">server.properties</a>에서 log.dirs 경로를 수정해주니 원래대로(home/min/data/kafka-logs) 재생성되는것을 확인할 수 있었습니다.초기화 후 지금까지 kafka디렉토리의 <a target="_blank" rel="noopener noreferrer nofollow" href="http://server.properties">server.properties</a>가 아닌 kraft 디렉토리의 <a target="_blank" rel="noopener noreferrer nofollow" href="http://server.properties">server.properties</a> 경로가 사용되고 있었던거 같더군요. 혹시 이유가 무엇인지 알 수 있을까요?

초기화 진행 후 카프카 구동이 안됩니다.
