Apache Oozie是一個開源的工作流和協作服務引擎，基于 Apache Hadoop 的數據處理任務。Oozie 是可擴展的、可伸縮的面向數據的服務，運行在Hadoop 平臺上。

Oozie 包括一個離線的Hadoop處理的工作流解決方案，以及一個查詢處理 API。

Oozie is a workflow/coordination system to manage Apache Hadoop(TM) jobs.

Oozie Workflow jobs are Directed Acyclical Graphs (DAGs) of actions.

Oozie Coordinator jobs are recurrent Oozie Workflow jobs triggered by time (frequency) and data availabilty.

Oozie is integrated with the rest of the Hadoop stack supporting several types of Hadoop jobs out of the box (Java map-reduce, Streaming map-reduce, Pig, Distcp, etc.)

Oozie is a scalable, reliable and extensible system.
