---------------------------------
Summary: Iceberg table operations hang a long time if metadata is
missing/corrupted
Key: HIVE-25563
URL: https://issues.apache.org/jira/browse/HIVE-25563
Project: Hive
Issue Type: Bug
Reporter: Ádám Szita
Assignee: 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:
