-------------------------------------
Summary: Hive ACID: Cleaner mishandles retries of killed
compactions
Key: HIVE-29420
URL: https://issues.apache.org/jira/browse/HIVE-29420
Project: Hive
Issue Type: Bug
Reporter: Denys Kuzmenko
Compaction retries triggered by timeouts under an incorrect configuration pose
a risk of data loss. If a compaction is re-attempted before the prior attempt
has completed or been properly aborted, the Cleaner may observe multiple base
directories with the same writeId and erroneously delete all of them.
