Chesnay Schepler commented on FLINK-28283:
------------------------------------------
I'm inclined to close this ticket; aggregations won't work, and hiding the log
message can already be achieved via log4j filters.
> Improving the log of flink when job start and deploy
> ----------------------------------------------------
>
> Key: FLINK-28283
> URL: https://issues.apache.org/jira/browse/FLINK-28283
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Task
> Affects Versions: 1.14.2
> Reporter: zlzhang0122
> Priority: Major
>
> When running a large job with many operators and subtasks on flink, the
> JobManager and TaskManager will have a huge logs about the subtask executing
> msg such as "XXX switched from CREATED to SCHEDULED、XXX switched from
> SCHEDULED to DEPLOYING 、XXX switched from DEPLOYING to RUNNING 、XXX switched
> from RUNNING to CANCELING、XXX switched from CANCELING to CANCELED", etc. .
> Maybe we can do some improvement about this, such as aggregate these msg to
> reduce the log, or change the log level and only logs the failure msg and
> subtask, etc. Not so sure about the solution, but these msg is really too
> much.
