Hive is een datawarehouse-tool die bovenop Hadoop is gebouwd. Het stelt gebruikers in staat om big data te analyseren die in een cluster zijn gedistribueerd met behulp van een SQL-achtige querytaal. In dit pad behandelen we de basisprincipes van datawarehouses met een specifieke focus op Hive. We onderzoeken hoe Hive-query's worden vertaald naar Hadoop MapReduce-taken onder de motorkap en behandelen de functies van Hive die het zo populair maken op het gebied van data-analyse. Dit pad behandelt ook de basisprincipes van Hive, zoals het maken, vullen en opvragen van tabellen, en bevat ook meer geavanceerde onderwerpen zoals het optimaliseren van query-uitvoeringen met behulp van partitionering en bucketing.
