> 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.
