Hi guys, just a short remark about the new logging system we use henceforth in Flink. We replaced jcl interface with slf4j and the log4j logging framework with logback. The only things which change for you is the generation of the logger and the configuration.
A logger with slf4j is created the following way: import org.slf4j.Logger; import org.slf4j.LoggerFactory; Logger LOG = LoggerFactory.getLogger(Foobar.class) In the context of this rework, we also disentangled Flink from the actually used logging framework. This means that we got rid off the LogUtils. A consequence of this change is that the logger is exclusively configured via the configuration file logback.xml. This file has to be placed in the classpath or given as an environment property -Dlogback.configurationFile=<file> to the JVM. Bests, Till
