About Oozie

Apache Oozie Workflow Scheduler for Hadoop is a workflow and coordination service for managing Apache Hadoop jobs:

  • Oozie Workflow jobs are Directed Acyclical Graphs (DAGs) of actions; actions are typically Hadoop jobs (MapReduce, Streaming, Pipes, Pig, Hive, Sqoop, etc).
  • Oozie Coordinator jobs trigger recurrent Workflow jobs based on time (frequency) and data availability.
  • Oozie Bundle jobs are sets of Coordinator jobs managed as a single job.

Oozie is an extensible, scalable and data-aware service that you can use to orchestrate dependencies among jobs running on Hadoop.

  Note: Running Services

Use the service command to start, stop, and restart CDH components, rather than running scripts in /etc/init.d directly. The service command creates a predictable environment by setting the current working directory to / and removing most environment variables (passing only LANG and TERM). With /etc/init.d, existing environment variables remain in force and can produce unpredictable results. When you install CDH from packages, service is installed as part of the Linux Standard Base (LSB).
