How to specify character set when creating a table in a hive?

In Hive, you can specify the character set by using the ROW FORMAT DELIMITED clause in the CREATE TABLE statement.

Here is an example:

CREATE TABLE my_table (
  col1 STRING,
  col2 INT
)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY ','
STORED AS TEXTFILE
LOCATION '/path/to/table'
TBLPROPERTIES ('charset'='utf8');

In the example above, the field delimiter is specified as a comma using the ROW FORMAT DELIMITED clause, and the character set is specified as UTF-8 using the TBLPROPERTIES clause. You can replace the character set with a different one according to your needs.

Please note that the character set specification method mentioned above applies to text file storage formats such as TEXTFILE. If you are using other storage formats like ORC or Parquet, you may need to use a different method to specify the character set. For more information, refer to the Hive documentation.
