Shammon created FLINK-25376:
-------------------------------

             Summary: Too many JM logs in flink session cluster for olap queries
                 Key: FLINK-25376
                 URL: https://issues.apache.org/jira/browse/FLINK-25376
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.14.2, 1.13.5, 1.12.7
            Reporter: Shammon


There're too many task/slot related log in jm when we submit small batch job to flink session cluster. The logs includes request slots, update task execution state and ect. In our benchmark the jm will generate a new log file in several minutes when the log file size is 500M, and some important logs will be overlapped. These logs is useful in flink stream/batch jobs, and should be changed to DEBUG level in flink olap mode.
