Purushottam Sinha updated FLINK-40118:
--------------------------------------
Description:
Problem
The job Timeline tab's SubTask view labels each subtask bar 0 - undefined, 1
- undefined, etc. instead of showing the host/endpoint the subtask ran on.
Evidence
-
flink-runtime-web/web-dashboard/src/app/pages/job/timeline/job-timeline.component.ts:135,141
builds the label as `${task.subtask} - ${task.host}`
- src/app/interfaces/job-timeline.ts:25 still declares the field as host:
string, so TypeScript compiles clean while task.host is undefined at runtime
- Root cause is backend/frontend drift, not a day-one bug: host was valid
when the dashboard was built in 2019 (dcd92958c58c). PR apache/flink#23465
(FLINK-33147, 2023-11-09) added endpoint alongside host, deprecating the
latter. PR apache/flink#25436 (FLINK-36355, merged 2024-10-01, commit
0b4de216d98 "Remove deprecated host") then deleted host from the REST response
entirely — that PR touched only backend Java classes and never updated the
Angular frontend, so task.host has read undefined ever since
- Confirmed still present on current master
Proposed fix
- job-timeline.ts:25: host: string → endpoint: string
- job-timeline.component.ts:135,141: ${task.host} → ${task.endpoint}
Acceptance
- SubTask TimeLine bars for a running job read N - localhost:PORT instead of
N - undefined
