Status: Patch Available (was: Open)
> Metastore throws NPE if StorageDescriptor.cols is null
> ------------------------------------------------------
>
> Key: HIVE-15353
> URL: https://issues.apache.org/jira/browse/HIVE-15353
> Project: Hive
> Issue Type: Bug
> Affects Versions: 1.1.0, 2.2.0
> Reporter: Anthony Hsu
> Assignee: Anthony Hsu
> Attachments: HIVE-15353.1.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.
> The simplest way to fix these NPEs seems to be to update the
> StorageDescriptor.cols Thrift definition and set a default value of empty
> list. Some null checks will also have to be added to handle existing nulls in
> the metastore database.
