> 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?
