Description
The HdfsParquetTableWriter needs to be aware that incoming data is clustered if the corresponding insert statement has a "clustered" hint. Only a single open partition should be maintained and flushed by calling FinalizePartitionFile() when the partition-key values change.
For now, no changes should be made to other table sinks.
