Summary: Add NoReconnect Annotation to Create
AlreadyExistsException Methods
Key: HIVE-25144
URL: https://issues.apache.org/jira/browse/HIVE-25144
Project: Hive
Issue Type: Improvement
Reporter: David Mollitor
Assignee: David Mollitor
I have recently seen an issue where a Hive {{CREATE TABLE}} method fails with
{{AlreadyExistsException}} even though the table does absolutely not exist.
I believe the issue is there there is a timeout/transient error with HMS and
the backend database. So, the client submits the request to HMS, and the
request does eventually succeed, but only after the connection to the client
connects. Therefore, when the HMS Client "retry" functionality kicks it, the
second time around, the table looks like it already exists.
If something goes wrong during a HMS CREATE operation, we do not know the state
of the operation and therefore it should just fail.
