Rajesh Balamohan created HIVE-27325:
---------------------------------------
Summary: Expiring old snapshots deletes files with
DirectExecutorService causing runtime delays
Key: HIVE-27325
URL: https://issues.apache.org/jira/browse/HIVE-27325
Project: Hive
Issue Type: Improvement
Reporter: Rajesh Balamohan
Expiring old snapshots takes a lot of time, as fileCleanupStrategy internally
uses directExecutorService. Creating this as a placeholder ticket to fix the
same. If fixed in iceberg, need to upgrade the lib here.
