To create an external table in Hive and specify the storage location, you can follow these steps:

  1. First, connect to the Hive server using the Hive command line interface or another Hive client.
  2. Create an external table using the CREATE EXTERNAL TABLE statement. Here is an example:
CREATE EXTERNAL TABLE my_external_table (
  column1 datatype1,
  column2 datatype2,
  ...
)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY ','
STORED AS TEXTFILE
LOCATION '/path/to/external/table';

In this example, my_external_table is the name of the table, column1 and column2 are the names of the columns, and datatype1 and datatype2 are the corresponding data types. You can customize the columns and data types according to your own needs.

ROW FORMAT DELIMITED specifies the format of the row, FIELDS TERMINATED BY ‘,’ specifies the delimiter between columns, and STORED AS TEXTFILE specifies the data storage format as a text file.

Specify the location of the external table with the location ‘/path/to/external/table’. Please ensure that this path is accessible on the Hive server.

This way, you can successfully create an external table and specify a storage location. You can insert data or query the table as needed.
