Peter Vary commented on HIVE-15353:

Hi [~erwaman],

Recently we created several MetaStore API tests. I think creating a table with 
null cols is tested here:


So most probably it is not possible to create a table like this anymore (at 
least not in 3.0.0 :) ).

>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: 1.1.0, 2.2.0
>            Reporter: Anthony Hsu
>            Assignee: Anthony Hsu
>            Priority: Major
>         Attachments: HIVE-15353.1.patch, HIVE-15353.2.patch, 
> HIVE-15353.3.patch, HIVE-15353.4.patch, HIVE-15353.5.patch
> When using the HiveMetaStoreClient API directly to talk to the metastore, you 
> get NullPointerExceptions when StorageDescriptor.cols is null in the 
> Table/Partition object in the following calls:
>  * create_table
>  * alter_table
>  * alter_partition
> Calling add_partition with StorageDescriptor.cols set to null causes null to 
> be stored in the metastore database and subsequent calls to alter_partition 
> for that partition to fail with an NPE.
> Null checks should be added to eliminate the NPEs in the metastore.
