prathamesh created FLINK-11018:
----------------------------------
Summary: Flink ignores logback.xml
Key: FLINK-11018
URL: https://issues.apache.org/jira/browse/FLINK-11018
Project: Flink
Issue Type: Bug
Components: Core
Affects Versions: 1.6.2
Reporter: prathamesh
Attachments: logback.xml
I am running flink locally on Windows as per instructions specified in the
[link documentation
|https://ci.apache.org/projects/flink/flink-docs-stable/start/flink_on_windows.html]
flink version: 1.6.1
The job i am running is the Sample Job
([https://ci.apache.org/projects/flink/flink-docs-release-1.6/quickstart/setup_quickstart.html#read-the-code]).
I am also configuring a logstash appender (logstash-logback-encoder) in order
to send the logs to a logstash instance running locally along with console and
file appenders.
When i run this flink job from my IDE, the logs are sent successfully to my
logstash instance. However when i submit the same job to my flink cluster, i
don't see any logs on logstash. Neither do i see any error indicating any
failure to create the logstash appender.
I am pretty sure the logstash appender works fine since it works when i run the
job from IDE. As per the [link Best
Practices|https://ci.apache.org/projects/flink/flink-docs-stable/dev/best_practices.html],
Flink uses log4j by default and needs to be configured to use logback. Does
this apply to flink logs as in Taskmanager and jobmanager logs or to
application logs?
Is flink ignoring the logback.xml file that gets packaged in my jar? How to get
flink to use the logback configuration that is included in the jar?
