I gave that a shot, but it didn't work. Could you run a describe table to
see if it matches this schema (assuming mysql):
--
-- Table structure for table `SDS`
--
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE IF NOT EXISTS `SDS` (
`SD_ID` bigint(20) NOT NULL,
`INPUT_FORMAT` varchar(4000) CHARACTER SET latin1 COLLATE latin1_bin
DEFAULT NULL,
`IS_COMPRESSED` bit(1) NOT NULL,
`LOCATION` varchar(4000) CHARACTER SET latin1 COLLATE latin1_bin DEFAULT
NULL,
`NUM_BUCKETS` int(11) NOT NULL,
`OUTPUT_FORMAT` varchar(4000) CHARACTER SET latin1 COLLATE latin1_bin
DEFAULT NULL,
`SERDE_ID` bigint(20) DEFAULT NULL,
PRIMARY KEY (`SD_ID`),
KEY `SDS_N49` (`SERDE_ID`),
CONSTRAINT `SDS_FK1` FOREIGN KEY (`SERDE_ID`) REFERENCES `SERDES`
(`SERDE_ID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
