Subject [jira] [Created] (FLINK-5192) Provide better log config templates
Date Tue, 29 Nov 2016 14:28:58 GMT
Ufuk Celebi created FLINK-5192:

             Summary: Provide better log config templates
                 Key: FLINK-5192
                 URL: https://issues.apache.org/jira/browse/FLINK-5192
             Project: Flink
          Issue Type: Improvement
          Components: JobManager, TaskManager
            Reporter: Ufuk Celebi
            Assignee: Ufuk Celebi

Our current log config template is very generic and invites users to always set the root logger
to DEBUG if they want to get more details. Since Flink depends on libraries like Akka and
it's common to run Flink with other systems like Hadoop or Kafka, this also increases the
log levels for those systems.

I would propose to split the default logger configuration up and provide a separate debugging
template. Furthermore, some noisy loggers might turned off by default, for example {{HadoopFileSystem}}.
