> In MetaStoreUtils.getPartSchemaFromTableSchema() the Propertie of a
> Partitions is first created by cloning the Properties from a Table. Then some
> of the properties are overwritten by the Partition level properties
> (Location/InputFormat/OutputFormat etc.). It also copies the properties from
> the SerDeInfo. If the SerDeInfo contains properties 'columns', 'column_types'
> and 'partition_columns' this will introduce incompatibility from the previous
> code path MetaStoreUtils.getSchema(). In getSchema(), the 'columns' etc are
> put after copying the SerDeInfo, which means we should not overwrite these 3
> properties in the new code.
