--------------------------------
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.
