----------------------------------
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}}.
