Description

To support the PARTITION clause of LOAD DATA INPATH the provided PartitionSpec should be analysed or worked around. Once that is done, a possible solution could be to modify the INSERT INTO SELECT statement to ingest the specified partition value, ie.:

INSERT INTO ... SELECT part_1, * FROM tmp_table;
