An introduction to Hive and Hadoop

The basics.

Getting data into Hive

Learn how to create tables in Hive, using the appropriate table properties and data types. Then we will cover
loading data into Hive from files on a local file system, files in HDFS or data in an RDBMS.

HiveQL

The Hive Query Language is an SQL-like language for querying data in Hadoop. It supports a subset of SQL-92
features, but also adds Hive/Hadoop-specific enhancements.

Query Execution

This section will explain how Hive converts queries into MapReduce code that is executed on the Hadoop cluster.

Partitioning and Bucketing

A powerful feature of Hive is the ability to partition and bucket your data. Partitioning is a way of organizing large
data sets into distinct subsets. Bucketing is useful for sampling a fraction of data.

Best Practices

These are specific recommendations for configuring Hive, handling data properly, and designing for performance.
