Apache Oozie 工作流调度器 for Hadoop

概述

Oozie是管理Hadoop作业（job)的工作流调度系统。

Oozie工作流作业是活动的有向无环图。

Oozie协调器作业是周期性的Oozie工作流作业，由时间（频率）和数据可用性触发。

Oozie能结合hadoop技术栈中其它项目，支持多种类型的即用型hadoop作业(例如Java map-reduce、Streaming map-reduce、Pig、Hive、Sqoop 和Distcp)，也可支持系统作业(例如Java程序和shell脚本)。

Oozie是一个可伸缩、可靠和可扩展的系统。

Apache Oozie Workflow Scheduler for Hadoop

Overview

Oozie is a workflow scheduler system to manage Apache Hadoop 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 (such as Java map-reduce, Streaming map-reduce, Pig, Hive, Sqoop and Distcp) as well as system specific jobs (such as Java programs and shell scripts).

Oozie is a scalable, reliable and extensible system.

Developers interested in getting more involved with Oozie may join the mailing lists, report bugs, retrieve code from the version control system, and make contributions.
