> Scheduler A Scheduler B | | RUNNING | | | Task starts | | | |--------------> SCHEDULED | | Heartbeat (409) | | | Task killed & retried | I’m new to open source and this is my first PR, so feedback is very welcome. > > While investigating an issue with multiple schedulers, I observed that a TaskInstance can regress from RUNNING back to SCHEDULED due to a race condition. This leads to heartbeat conflicts (409), premature task termination, and repeated task retries. > > This PR adds a small guard in TaskInstance.set_state() to prevent the invalid RUNNING → SCHEDULED transition while allowing all valid state transitions. This avoids killing already-running tasks and preserves correct execution. > > Tested locally with a multi-scheduler setup. @abhijeets25012-tech I can't find the PR you're mentioning? -- This is an automated message from the Apache Git Service.
