kbuci opened a new pull request, #18012:
URL: https://github.com/apache/hudi/pull/18012
### Describe the issue this Pull Request addresses
Updated compact to start a heartbeat (within a transaction) before
attempting to execute a plan. If multiple writers attempt to execute same
compact/logcompact plan at same time, only one of them will process and the
rest will fail with an exception (upon seeing a heartbeat has already been
started) and will abort.
### Summary and Changelog
Without this change, if multiple jobs are launched at the same that target
executing the same compact plan (due to a non-HUDI related user-side
configuration/orchestration issue) then one job can execute the compact plan
and create an inflight/commit instant file while the other jobs can roll it
back (and delete inflight instant files or data files). This can lead to
timeline being in a corrupted state.
