Apache Oozie™ is a workflow scheduler system to manage Apache Hadoop jobs. Using Oozie, you can set up workflows that execute MapReduce jobs and coordinators that manage workflows.
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).
This section contains the following documentation for Oozie on the MapR distribution for Apache Hadoop:
It provides all relevant details about using Oozie with MapR, but does not duplicate Apache documentation. You can refer also to documentation available from the Apache Oozie project.
