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 {{{./mail-lists.html}mailing lists}}, {{{https://issues.apache.org/jira/browse/OOZIE}report bugs}}, retrieve code from the {{{./source-repository.html}version control system}}, and make {{{https://cwiki.apache.org/confluence/display/OOZIE/How+To+Contribute}contributions}}.
