Description: The value of the prevbit parameter must be greater than or equal to -1 when the parameter is verified.
Solution:Contact technical support.
GAUSS-04708: "Column count in table definition does not match with ORC file %s."
SQLSTATE: 22000
Description: The column definition of the table is inconsistent with that of the ORC file.
Solution:Contact technical support.
GAUSS-04709: "Error occurs while read row index of orc file, detail can be found in dn log of %s."
SQLSTATE: 22000
Description: An error occurs when the index data in the ORC file on the DFS is read.
Solution:Contact technical support.
GAUSS-04710: "Unsupported orc type : %u."
SQLSTATE: 0A000
Description: The DFS table does not support this data type.
Solution:Contact technical support.
GAUSS-04711 - GAUSS-04720
GAUSS-04714: "Unsupported data type : %u."
SQLSTATE: 0A000
Description: The HDFS table does not support this data type.
Solution: Change the definition type to the type that the HDFS table supports based on the prompt.
GAUSS-04715: "Invalid string for 'COMPRESSION' option."
SQLSTATE: 22023
Description: The compression mode is invalid.
Solution: Set a correct compression mode when creating a table. The HDFS supports only the zlib or snappy compression algorithm.
GAUSS-04721 - GAUSS-04730
GAUSS-04721: "The start index is over the limit."
SQLSTATE: 22000
Description: The imported data exceeds the maximum data volume in the buffer process when the HDFS table is imported and the upper-layer data is written to the bottom data stream.
Solution: Check specific reason information in the corresponding DN logs.
GAUSS-04722: "DFS connector can not be NULL when loading data into dfs table."
SQLSTATE: 42704
Description: The HDFS connection to DFS is an invalid pointer when data is imported to the HDFS.
Solution:Contact technical support.
GAUSS-04726: "We only support pushing down opExpr and null test predicate."
SQLSTATE: 0A000
Description: The type of the filter predicates in the HDFS table is not supported.
Solution:Contact technical support.
GAUSS-04727: "could not find operator by oid %u"
SQLSTATE: 42704
Description: Internal system error. Failed to query the operation type through OID.
Solution:Contact technical support.
GAUSS-04728: "Not support pushing predicate with sublink param now!"
SQLSTATE: 0A000
Description: Internal system error. The predicate of the subquery cannot be pushed down.
Solution:Contact technical support.
GAUSS-04729: "Not support pushing predicate with non-const"
SQLSTATE: 0A000
Description: Internal system error. The non-constant predicate cannot be pushed down.
Solution:Contact technical support.
GAUSS-04730: "We only support pushing down opExpr and null test predicates."
SQLSTATE: 0A000
Description: Internal system error. Only the expression predicate and the null predicate can be pushed down.
Solution:Contact technical support.
GAUSS-04731 - GAUSS-04740
GAUSS-04731: "Data type %u has not been supported for predicate push down."
SQLSTATE: 0A000
Description: Internal system error. The error data type does not support dynamic predicate pushdown.
Solution:Contact technical support.
GAUSS-04732: "The maximum accuracy of decimal/numeric data type supported is %d bits."
SQLSTATE: 0A000
Description: The maximum precision supported by the decimal or numeric type exceeds 38 digits.
Solution: Define the precision of the decimal or numeric type to be less than or equal to 38 digits when creating a table.
GAUSS-04737: "There is an illegal character '%c' in the option %s."
SQLSTATE: 44000
Description: Invalid characters exist in the option of folder name or file name.
Solution: Check the path specification of the folder name or file name and rebuild the HDFS foreign table.
GAUSS-04738: "The option %s should not be end with '%c'."
SQLSTATE: 44000
Description: An error is reported when the option of the file name ends up with a slash (/).
Solution: Do not end up the option of the file name with a slash (/).
GAUSS-04741 - GAUSS-04750
GAUSS-04741: "The path '%s' must be an absolute path."
SQLSTATE: 42P17
Description: The path of the file name or folder name is not an absolute path.
Solution: The folder name or file name specified for an HDFS table must be an absolute path.
GAUSS-04742: "The address option exists illegal character: '%c'"
SQLSTATE: 44000
Description: Invalid spaces exist in the address option of the server on the HDFS.
Solution: Remove the invalid spaces.
GAUSS-04744: "The count of address '%s' must be not greater than %d."
SQLSTATE: 44000
Description: The number of the addresses cannot exceed 2.
Solution: Ensure that the number of addresses specified during DFS server creation does not exceed 2.
GAUSS-04745: "Unsupport ipv6 foramt"
SQLSTATE: 44000
Description: The address of the DFS server does not support the IPv6 address format.
Solution: Change the address of the DFS server to the IPv4 address format.
GAUSS-04746: "The incorrect address format"
SQLSTATE: 44000
Description: The address format is incorrect.
Solution: View the correct address description.
GAUSS-04747: "Failed to create DfsInsert handler when updating table."
