There are two ways to set the encoding format in Hive.

  1. Specify the encoding when creating the table:
  2. Create a table with the name “table_name” containing one column named “column1” with the specified data type and comment. The table itself will have a table comment and will be stored as a text file with tab-separated fields.
  3. In the code above, specifying STORED AS TEXTFILE sets the storage format of the table as a text file, allowing for the adjustment of the encoding format. For instance, to use UTF-8 encoding, you can modify it to STORED AS TEXTFILE LOCATION ‘/path/to/table’ TBLPROPERTIES (‘textfile.encoding’=’UTF-8’);
  4. Change the default encoding format of Hive:
    In the Hive configuration file hive-site.xml, you can modify the default encoding format of Hive by setting the following property.
  5. hive.default.fileformat
    TextFile     hive.textfile.encoding
    UTF-8
  6. In the code above, hive.default.fileformat specifies the default storage format for tables as text files, and hive.textfile.encoding specifies the default encoding format as UTF-8. You can modify the values of these two properties as needed to set the encoding format.

Please select the appropriate method for setting the encoding format based on your specific needs.
