[HADOOP] Log4j가 HDFS / Log4j.properties에 쓰지 않음

Log4j가 HDFS / Log4j.properties에 쓰지 않음

다음 구성을 기반으로 log4j가 HDFS 폴더 (/ myfolder / mysubfolder)에 기록해야합니다. 그러나 주어진 이름의 hadoop9.log로 파일을 작성하지도 않습니다. hdfs에서 수동으로 hadoop9.log를 작성하여 시도했습니다. 여전히 작동하지 않았습니다.

log4j.properties에 누락 된 것이 있습니까?

해결법

1. ==============================

   1.RollingFileAppender는 로컬 디스크에만 기록합니다. 어떻게 든 HDFS를 마운트하여 "OS의 로컬 디스크처럼"작동하지 않을 수 있습니다. Flume Appender와 같은 원격 로깅을 지원하는 다른 Log4j Appender 유형을 선택하거나 직접 롤업해야합니다.
