Subject [jira] [Commented] (HIVE-4467) HiveConnection does not handle failures correctly
Date Wed, 01 May 2013 22:22:16 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13647003#comment-13647003

Carl Steinbach commented on HIVE-4467:
--------------------------------------

The HS2 API is modeled on the [SQL/CLI standard|http://en.wikipedia.org/wiki/SQL/CLI]. In
most cases SQL/CLI is interchangeable with ODBC, so most answers about why things are structured
the way they are can be answered by consulting the ODBC API documentation. Here's the relevant
page for SUCCESS_WITH_INFO: http://msdn.microsoft.com/en-us/library/windows/desktop/ms716219(v=vs.85).aspx

> HiveConnection uses Utils.verifySuccess* routines to check if there is any error from
the server side. This is not handled well. In Utils.verifySuccess() when withInfo is 'false',
the condition evaluates to 'false' and no SQLexception is thrown even though there could be
a problem on the server.
