> Improve Logging for SemanticException Handling
> ----------------------------------------------
>                 Key: HIVE-19190
>                 URL: https://issues.apache.org/jira/browse/HIVE-19190
>             Project: Hive
>          Issue Type: Improvement
>          Components: HiveServer2
>    Affects Versions: 3.0.0, 2.3.2
>            Reporter: BELUGA BEHR
>            Priority: Major
> Please improve the logging for queries that fail with SemanticException.  For 
> example, when performing an action on a table that does not exist.  The most 
> common reason why this happens is that someone fat fingers the table/column 
> name.  It is not a system error pe se, but a user validation error.  This is 
> not something the cluster administrator should have to worry about.  Yet, 
> Hive performs some pretty extreme logging on the matter.  I have attached to 
> this JIRA the logging produced by a single submission of the following query:
> {code:sql}
> select * from madeup';
> {code}
> For SemanticException exceptions, please print the Exception {{getMessage()}} 
> to the server INFO logging so that the query's life-cycle can be traced, but 
> do not blast ERRORs and stack traces to the log file.
