GAUSS-04711 -- GAUSS-04720

GAUSS-04711: "Unsupported data type : %u."

SQLSTATE: 0A000

Description: The HDFS table does not support this data type.

Solution: Based on the prompt, change the definition type to the type that the HDFS table supports.

GAUSS-04712: "Invalid string for 'COMPRESSION' option."

SQLSTATE: 22023

Description: The compressed mode is invalid.

Solution: Set a correct compressed mode when creating a table. The HDFS supports only the zlib or snappy compression algorithm.

GAUSS-04713: "Failed to create partition directory %s when loading data to partitioned DFS table"

SQLSTATE: 08000

Description: The partition directory fails to be created when data is imported to the HDFS partitioned table.

Solution: Check specific reason information in the corresponding DN log. In most cases, this error occurs because the user permissions are insufficient.

GAUSS-04714: "Error occurs while opening a new file, detail can be found in dn log of %s."

SQLSTATE: 08000

Description: A new file fails to be created on the DFS when the HDFS table is imported.

Solution: Check specific reason information in the corresponding DN log. Probably an error occurs in the HDFS cluster or the permission is insufficient.

GAUSS-04715: "Error occurs while spilling a new file to write, detail can be found in dn log of %s."

SQLSTATE: XX000

Description: Data fails to be written to the DFS file when the HDFS table is imported.

Solution: Check specific reason information in the corresponding DN log.

GAUSS-04716: "Error occurs while add a column batch, detail can be found in dn log of %s."

SQLSTATE: 22000

Description: The buffer process of writing the upper-layer data to the bottom-layer data flow fails when the HDFS table is imported.

Solution: Check specific reason information in the corresponding DN log.

GAUSS-04717: "Error occurs while close the orc writer, detail can be found in dn log of %s."

SQLSTATE: 22000

Description: A new written DFS file fails to be closed when the HDFS table is imported.

Solution: Check specific reason information in the corresponding DN log.

GAUSS-04718: "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 log.

GAUSS-04719: "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-04420: "Invalid Oid for operator %d."

SQLSTATE:20000

Description: The operation function of this type cannot be found when the filtering predicates are constructed based on the column type of an HDFS table.

Solution: Contact technical support. Alternatively, check whether this type has corresponding operation function in pg_opclass.
