This page shows how to create a temporary Hive table via Hive SQL (HQL).
Create temporary table
CREATE TEMPORARY TABLE temp_customer (`cust_id` int, `name` string,`created_date` date) STORED AS PARQUET;
Temporary Hive tables are only visible to the creation session and will be deleted automatically when the session ends. The underlying data is stored in user scratch folder (/tmp/hive/$USERID/*).

The terminal looks like the following screenshot:
