>                 Key: HIVE-22529
>                 URL: https://issues.apache.org/jira/browse/HIVE-22529
>             Project: Hive
>          Issue Type: Improvement
>            Reporter: David Mollitor
>            Assignee: David Mollitor
>            Priority: Major
>
> In some places, the following DEBUG logging was introduced:
> {code:java}
> LOG.debug("Message", new Exception());
> {code}
> The purpose of this is to log the stack trace of the Thread calling this debug logging
method.  However, the resulting log message includes the following:
> {code:none}
> 2019-11-19T08:13:31,392 DEBUG [Thread] Logger: Message
> java.lang.Exception: null
>  at ....
> {code}
> To the observer, it appears that there was perhaps some sort of NPE.  Add a message to
the Exception being generated to make it more clear that this "Exception" is for debugging
purposes and not an actual error.
