Ferdinand Xu commented on HIVE-11579:
-------------------------------------
Thanks [~xuefuz] for the review. The tmp files are used to redirection in the
server side. It's not used for the console(client side). That's the reason it
doesn't close the system err output stream in non embedded mode.
> Invoke the set command will close standard error output[beeline-cli]

> Project: Hive
> Issue Type: Sub-task
> Components: CLI

> We can easily reproduce the debug by the following steps:
> {code}
> hive> set system:xx=yy;
> hive> lss;
> hive>
> {code}
> The error output disappeared since the err outputstream is closed when
> closing the Hive statement.
> This bug occurred also in the upstream when using the embeded mode as the new
> CLI uses.
