CalvinKirs opened a new pull request, #45446:
URL: https://github.com/apache/doris/pull/45446
### What problem does this PR solve?
When the Master node restarts or switches to a new primary, the new Master
must take over task scheduling. In this scenario, tasks running on the previous
Master may remain in an uncertain state (e.g., suspended or incomplete). To
ensure system consistency and accurate task states, the new Master should
enforce failure handling for these tasks after its initialization to clean up
any residual task states.
