Oozie Guide

Apache Oozie Workflow Scheduler for Hadoop is a workflow and coordination service for managing Apache Hadoop jobs:

• Oozie Workflow jobs are Directed Acyclical Graphs (DAGs) of actions; actions are typically Hadoop jobs (MapReduce, Streaming, Pipes, Pig, Hive, Sqoop, etc).
• Oozie Coordinator jobs trigger recurrent Workflow jobs based on time (frequency) and data availability.
• Oozie Bundle jobs are sets of Coordinator jobs managed as a single job.

Oozie is an extensible, scalable and data-aware service that you can use to orchestrate dependencies among jobs running on Hadoop.
