Subject [jira] [Commented] (HIVE-11579) Invoke the set command will close standard error output[beeline-cli]
Date Tue, 18 Aug 2015 02:36:45 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11579?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14700648#comment-14700648

Ferdinand Xu commented on HIVE-11579:
-------------------------------------

When I am debuging, I see the error output is closed after invoking the closeClientOperation
method in class HiveStatement. The main purpose for this method is to send a request to the
server to close handler. You can see that the error output is redirected to the standard error
output. When the SQLOperation closes a driver, it will close the driver with resStream closed.
When in the non-embedded mode, it works well since the two output stream are not the same
one while it failed for embedded mode.

> 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.
