Anthony Hsu updated HIVE-15353:
-------------------------------
Description:
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.

* 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.
