Starting, Stopping, and Accessing the Oozie Server

Starting the Oozie Server

After you have completed all of the required configuration steps, you can start Oozie: 

$ sudo service oozie start

If you see the message Oozie System ID [oozie-oozie] started in the oozie.log log file, the system has started successfully.

  Note:

By default, Oozie server runs on port 11000 and its URL is http://<OOZIE_HOSTNAME>:11000/oozie.

Stopping the Oozie Server

$ sudo service oozie stop

Accessing the Oozie Server with the Oozie Client

The Oozie client is a command-line utility that interacts with the Oozie server via the Oozie web-services API.

Use the /usr/bin/oozie script to run the Oozie client.

For example, if you want to invoke the client on the same machine where the Oozie server is running: 

$ oozie admin -oozie http://localhost:11000/oozie -status
System mode: NORMAL

To make it convenient to use this utility, set the environment variable OOZIE_URL to point to the URL of the Oozie server. Then you can skip the -oozie option.

For example, if you want to invoke the client on the same machine where the Oozie server is running, set the OOZIE_URL to http://localhost:11000/oozie. 

$ export OOZIE_URL=http://localhost:11000/oozie
$ oozie admin -version
Oozie server build version: 4.0.0-cdh5.0.0
  Important:

If Oozie is configured with Kerberos Security enabled:

  • You must have a Kerberos session running. For example, you can start a session by running the kinit command.
  • Do not use localhost as in the above examples.

As with every service that uses Kerberos, Oozie has a Kerberos principal in the form <SERVICE>/<HOSTNAME>@<REALM>. In a Kerberos configuration, you must use the <HOSTNAME> value in the Kerberos principal to specify the Oozie server; for example, if the <HOSTNAME> in the principal is myoozieserver.mydomain.com, set OOZIE_URL as follows: 

$ export OOZIE_URL=http://myoozieserver.mydomain.com:11000/oozie

If you use an alternate hostname or the IP address of the service, Oozie will not work properly.

Accessing the Oozie Server with a Browser

If you have enabled the Oozie web console by adding the ExtJS library, you can connect to the console at http://<OOZIE_HOSTNAME>:11000/oozie.

  Note:

If the Oozie server is configured to use Kerberos HTTP SPNEGO Authentication, you must use a web browser that supports Kerberos HTTP SPNEGO (for example, Firefox or Internet Explorer).
