Starting and Stopping Oozie Services

The Warden daemon starts the Oozie server automatically at installation time. You can start and stop Oozie from the command line or from the MapR Control System. Using the maprcli node services command enables you to start Oozie on multiple nodes at one time.

WARNING: Whenever you change the cluster MapReduce mode (from Yarn to Classic, or from Classic to Yarn), you must restart the Oozie server.

Starting and Stopping Oozie using maprcli

Complete the following steps to start|stop Oozie from the command line:

  1. Make a list of nodes on which Oozie is configured.
  2. Issue the maprcli node services command with either start or stop, and specify the nodes on which Oozie is configured, separated by spaces.
    Example:
    maprcli node services -name oozie -action start -nodes node001 node002 node003
    maprcli node services -name oozie -action stop -nodes node001 node002 node003
