Apache Oozie - Workflow Scheduler for Hadoop

Oozie is a workflow scheduler system to manage Apache Hadoop jobs. Its jobs are Directed Acyclical Graphs (DAGs) of actions and triggered by time (frequency) and data availability. 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).
