How to resolve errors when adding bulk data in Hive?

If there is an error when Hive adds data in bulk, you can try the following solutions:

1. Verify that the format and file type of the input data are correct, ensuring that the columns of the data file correspond with the columns of the Hive table, and that the data format aligns with the table structure definition.
2. Check if the path to the data file is correct, including confirming if the file path exists and if it is spelled correctly.
3. Check the permissions of the data files to ensure that Hive users have sufficient privileges to read the data files.
4. Check if the data file is corrupted by using other tools or commands to verify the integrity of the data file.
5. To avoid potential network transfer issues, you can try using the LOAD DATA INPATH command in Hive instead of the LOAD DATA LOCAL INPATH command.
6. Check the storage format and table partition settings of Hive to ensure that the table structure is consistent with the structure of the data files.
7. Check the relevant parameters in the Hive configuration file, such as hive.exec.dynamic.partition.mode, hive.exec.dynamic.partition, hive.exec.max.dynamic.partitions, hive.exec.max.dynamic.partitions.pernode, etc., to ensure that the configuration is correct and meets the requirements.
8. You can check if the Hive metadata is correct by trying to recreate the table or repairing the metadata.

If the above methods do not solve the issue, you can check the specific error messages and logs to pinpoint the problem more accurately and proceed with debugging.
