[jira] [Created] (FLINK-12683) Provide task manager's location information for checkpoint acknowledge message to improve the checkpoint log message

vinoyang created FLINK-12683:
--------------------------------

             Summary: Provide task manager's location information for checkpoint acknowledge message to improve the checkpoint log message
                 Key: FLINK-12683
                 URL: https://issues.apache.org/jira/browse/FLINK-12683
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Checkpointing
            Reporter: vinoyang
            Assignee: vinoyang


Currently, the {{AcknowledgeCheckpoint}} does not contain the task manager's location information. When a task's snapshot task sends an ack message to the coordinator, we can only log this message:
{code:java}
Received late message for now expired checkpoint attempt 6035 from ccd88d08bf82245f3466c9480fb5687a of job 775ef8ff0159b071da7804925bbd362f.
{code}
Sometimes we need to get this sub task's location information to do the further debug work, e.g. stack trace dump. But, without the location information, It will not help to quickly locate the problem.
