Worklog Time Spent: 10m
Work Description: szlta opened a new pull request #2676:
URL: https://github.com/apache/hive/pull/2676
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.
We should make the retry count configurable, and with a lower default
setting.
