TEZ-4559: Fix Retry logic in case of Recovery #353

@abstractdog abstractdog commented May 6, 2024

Some unit tests were broken by TEZ-4543, where we simply returned a failed DAG if the requested DAG status cannot be found. This completely breaks recovery scenarios where the dagClient might keep asking for the failed DAGs status (while the AM restarts after a failure).

Considering recovery works, the client should simply consider if recovery is enabled and behave accordingly. This patch reverts the behavior in case of recovery to pre-TEZ-4543, but if there is no recovery, TEZ-4543 is a fair assumption and still makes the client able to return much faster in case of the specialized exception implying that the DAG is already lost.

Unit tests have been run manually with this patch: TestDAGRecovery, TestAMRecovery, TestRecovery
