David Robinson created AURORA-275:
-------------------------------------

             Summary: Scheduler logs do not have a consistent format
                 Key: AURORA-275
                 URL: https://issues.apache.org/jira/browse/AURORA-275
             Project: Aurora
          Issue Type: Task
          Components: Scheduler
            Reporter: David Robinson
            Priority: Minor


The logs produced by the scheduler do not have a consistent format. The time field sometimes shows milliseconds and sometimes microseconds. The PID field sometimes shows THREAD123456 and sometimes 123456. The 'where' field (line of source code) is also inconsistent. I suspect the inconsistencies are due to the C++ components (mesos scheduler driver) using one format and the Java components (scheduler) using another. It would be great if a single format were used -- it would make parsing logs much simpler (the year being present in the logs would also help)!
