Robert Metzger reopened FLINK-17295:
------------------------------------
Assignee: (was: Yangze Guo)
I opened a PR to revert this change: https://github.com/apache/flink/pull/13892
As you can read in FLINK-19805, we found that the ExecutionAttemptID proposed
in this change so far does not work well with leader changes: It can happen
that ExecutionAttemptID from leader 1 will report status updates (failures) to
leader 2, which will then fail with an unexpected message.
There are different ideas how to solve this problem:
a) Add (part of the) leader id to the ExecutionAttemptID (complicated to wire
into the ExecutionAttemptID generation)
b) Include a random element in the ExecutionAttemptID
c) Introduce a random element in the ExecutionGraph (executionAttemptId) and
forward that to each ExecutionAttemptID.
> Refactor the ExecutionAttemptID to consist of ExecutionVertexID and
> attemptNumber
