------------------------------
Status: Patch Available (was: Open)
> Iceberg table operations hang a long time if metadata is missing/corrupted

> Key: HIVE-25563

> Project: Hive
> Issue Type: Bug
> Reporter: Ádám Szita

> For all Iceberg table operations (select, insert, alter, etc..) Hive tries to
> load the Iceberg table by reading in its metadata files.
> If these metadata files are not present or are inaccessible for any reason,
> then operations on such a table will result in a long > 10 minutes hang for
> the user's session. This is because there's a retry logic with exponential
> intervals, and 21 retries by default in place:
