Zhu Zhu updated FLINK-27710:
----------------------------
Description:
Currently, an execution is usually represented as "{{{}job vertex name{}}}
({{{}subtaskIndex+1{}}}/{{{}vertex parallelism{}}}) ({{{}attemptId{}}})" in
logs, which may be redundant after this refactoring work. With the change of
FLINK-17295, the representation of Execution in logs will be redundant. e.g.
the subtask index is displayed 2 times.
Therefore, I'm proposing to change the format to be "<{{{}job vertex name>
{}}}(<{{{}subtaskIndex>+1{}}}/<{{{}vertex parallelism>{}}})
{{#<attemptNumber>}} (graph: <{{{}short ExecutionGraphID>, vertex:
<{}}}{{{}JobVertexID>{}}}) " and avoid directly display the
{{{}ExecutionAttemptID{}}}. This can increase the log readability.
Besides that, the displayed {{JobVertexID}} can also help to distinguish job
vertices of the same name, which is common in DataStream jobs (e.g. multiple
{{{}Map{}}}).
