Hive for Beginners teaches you to ask questions about stored files using Apache Hive and SQL. Starting with a small retailer's orders, you will connect CSV data to tables, calculate paid sales, and deliver a regional report you can rebuild.
The course combines 8 Guided Labs with 2 Challenges. Guided Labs introduce concepts before their use; Challenges apply those skills to new inputs. Small datasets let you check the answer by hand before trusting a query.
What You Will Learn
After completing this course, you will be able to:
- inspect table columns and run saved SQL through Beeline;
- map CSV files to external tables and distinguish metadata from stored records;
- filter rows, handle NULL values, and calculate decimal sales aggregates;
- join customer data and check whether matching keys preserve the intended rows;
- register date partitions and inspect which partitions a query selects;
- rebuild ORC result tables without accumulating duplicates and diagnose parsing, location, and partition problems.
Who This Course Is For
This course is for beginners in data analysis or data engineering who want to query file-based data and build repeatable batch reports.
Prerequisites: Basic terminal use and the ability to read a table. No prior SQL, Hadoop, Java, or Python knowledge is required.
Learning environment: LabEx provides a browser-based Linux terminal with Hive, HDFS, and the required services prepared. Each activity supplies its own data; production cluster administration is outside the course.
Frequently Asked Questions
Do I need to learn SQL or finish the Hadoop course first?
No. Basic terminal use and the ability to read a table are enough; the course introduces the SQL it uses. Taking Hadoop first gives useful context about HDFS storage, but each Hive activity prepares its own environment and data.
How is Hive different from the Hadoop operations taught earlier?
Hadoop practice focuses on files and batch jobs. Here, Hive maps stored files to tables so you can query them with SQL and build sales reports. You learn how table metadata, file locations, and partitions relate.
Do I need to install Hive or connect to a company database?
No. LabEx supplies Hive, its required services, and practice datasets in the browser environment. You work with prepared retail files and tables; no company data or production cluster is required.
