ArnavBalyan opened a new pull request, #8142:
URL: https://github.com/apache/paimon/pull/8142
### Purpose
- Today, any hive job writing to Paimon table failing before precommit,
causes job to be permanently stuck and does not exit cleanly.
- This is because Paimon throws another exception in the cleanup process
when there are no files to be cleaned up. Paimon throws unchecked runtime
exception not caught at caller.
- This causes the parent thread to be permanently stuck waiting job failure
to arrive (which does not happen since the runtime exception was not caught by
hadoop).
- Ensure that we don't do unprotected access, and can handle exceptions
when there are no precommit files produced.
- This also fixes an issue of CI being stuck and timing out in some cases
when the UT has a failure.
### Tests
- UT
