----------------------------------
Resolution: Fixed
> NPE in GenericUDFToUnixTimeStamp
> --------------------------------
>
> Key: HIVE-24113
> URL: https://issues.apache.org/jira/browse/HIVE-24113
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 3.1.2
> Reporter: Rajkumar Singh
> Assignee: Rajkumar Singh
> Priority: Major
>
> Following query will trigger the getPartitionsByExpr call at HMS, HMS will
> try to evaluate the filter based on the PartitionExpressionForMetastore
> proxy, this proxy uses the QL packages to evaluate the filter and call
> GenericUDFToUnixTimeStamp.
> select * from table_name where hour between
> from_unixtime(unix_timestamp('2020090120', 'yyyyMMddHH') - 1*60*60,
> 'yyyyMMddHH') and from_unixtime(unix_timestamp('2020090122', 'yyyyMMddHH') +
> 2*60*60, 'yyyyMMddHH');
> I think SessionState in the code path will always be NULL thats why it hit
> the NPE.
> {code:java}
> java.lang.NullPointerException: null
