> 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.
