Stephan Ewen commented on FLINK-4820   Re: Slf4j / log4j version upgrade to support dynamic change of log levels. After a discussion with Robert Metzger, we decided to initially simply make Flink completely independent of a specific logging framework. We keep bundling log4j 1.x in flink-dist to not break all existing setups (log4j 2.x is config incompatible with log4j 1.x). Users can simply use log4j 2 instead by replacing the log4j-1.2.17.jar and slf4j-log4j12-1.7.7.jar with the log4j2 jar files (the same ways as using logback instead of log4j) Add Comment   This message was sent by Atlassian JIRA (v6.3.15#6346-sha1:dbc023d)
