The command hive -e "${hiveql_query}" is used to execute a HiveQL query using the Hive CLI (Command Line Interface).

Let's break down the command:

• hive is the command to run the Hive CLI.
• -e is a flag that specifies the option to execute a single HiveQL query.
• ${hiveql_query} is a variable that holds the HiveQL query to be executed. The $ symbol indicates a variable in bash or shell scripts.

By using this command, you can pass a HiveQL query as a string to the ${hiveql_query} variable, and the query will be executed in Hive. This allows you to run HiveQL queries without the need for an interactive Hive shell.
