cannot specify multiple hive partition key using sqoop import

sqoop-import --connect jdbc:mysql://ip/db --username user -P --table tb --hive-table tb --hive-import \
--hive-paritition-key key1 --hive-partition-value value1 \
--hive-paritition-key key2 --hive-partition-value value2

The above command only deals with the first partition configuration and ignores the second one.
