[jira] [Commented] (HIVE-12196) NPE when converting bad timestamp value

["Aihua Xu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-12196?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14987858#comment-14987858 ] 

Aihua Xu commented on HIVE-12196:
---------------------------------

Simple fix which will check the value after the conversion. If it's null, return null. So if the timestamp is not correct, it will generate a null value.

> When I convert a timestamp value that is slightly wrong, the result is a NPE. Other queries correctly reject the timestamp:
> {code}
> hive> select from_utc_timestamp('2015-04-11-12:24:34.535', 'UTC');
> FAILED: NullPointerException null
> hive> select TIMESTAMP '2015-04-11-12:24:34.535';
> FAILED: SemanticException Unable to convert time literal '2015-04-11-12:24:34.535' to time value.
> {code}
