Oozie provides a command line utility, oozie , to perform job and admin tasks. All operations are done via sub-commands of the oozie CLI.
The oozie CLI interacts with Oozie via its WS API.

All oozie CLI sub-commands expect the -oozie OOZIE_URL option indicating the URL of the Oozie system to run the command against.
If the -oozie option is not specified, the oozie CLI will look for the OOZIE_URL environment variable and uses it if set.
If the option is not provided and the environment variable is not set, the oozie CLI will fail.
Example:
$ oozie job -oozie http://localhost:8080/oozie -config job.properties -submit . job: 14-20090525161321-oozie-tucu
The parameters for the job must be provided in a file, either a Java Properties file (.properties) or a Hadoop XML Configuration file (.xml). This file must be specified with the -config option.
The workflow application path must be specified in the file with the oozie.wf.application.path property. The coordinator application path must be specified in the file with the oozie.coord.application.path property. Specified path must be an HDFS path.
The job will be created, but it will not be started, it will be in PREP status.
Example:
$ oozie job -oozie http://localhost:8080/oozie -start 14-20090525161321-oozie-tucu
The start option starts a previously submitted workflow job or coordinator job that is in PREP status.
After the command is executed the workflow job will be in RUNNING status and coordinator job will be in PREMATER status.
Example:
$ oozie job -oozie http://localhost:8080/oozie -config job.properties -run . job: 15-20090525161321-oozie-tucu
The run option creates and starts a workflow job or coordinator job.
The parameters for the job must be provided in a file, either a Java Properties file (.properties) or a Hadoop XML Configuration file (.xml). This file must be specified with the -config option.
The workflow application path must be specified in the file with the oozie.wf.application.path property. The coordinator application path must be specified in the file with the oozie.coord.application.path property. The specified path must be an HDFS path.
The job will be created and it will started, the job will be in RUNNING status.
Example:
$ oozie job -oozie http://localhost:8080/oozie -suspend 14-20090525161321-oozie-tucu
The suspend option suspends a job in RUNNING status.
After the command is executed the job will be in SUSPENDED status.
When the coordinator job is suspended, running coordinator actions will stay in running and the workflows will be suspended.
Example:
$ oozie job -oozie http://localhost:8080/oozie -resume 14-20090525161321-oozie-tucu
The resume option resumes a job in SUSPENDED status.
After the command is executed the job will be in RUNNING status.
When a coordinator job is resumed, it will transition to the status from which it was suspended, if it was RUNNING it cannot transition to PREP .
When the coordinator job is resumed it will create all the coordinator actions that should have been created during the time it was suspended, actions will not be lost, they will delayed.
Example:
$ oozie job -oozie http://localhost:8080/oozie -kill 14-20090525161321-oozie-tucu
The kill option kills a workflow job in PREP , SUSPENDED or RUNNING status and a coordinator job in =PREP=, PREMATER , SUSPENDED or RUNNING status.
After the command is executed the job will be in KILLED status.
Example:
$ oozie job -oozie http://localhost:8080/oozie -change 14-20090525161321-oozie-tucu -value endtime=2011-12-01T05:00Z\;concurrency=100\;2011-10-01T05:00Z
The change option changes a coordinator job that is not in KILLED status.
Valid value names are:
Repeated value names are not allowed. New end time must not be before job's start time and last action time. New concurrency value has to be a valid integer. New pause time must not be before job's start time and last action time and must be before job's end time. Also empty string "" can be used to reset pause time to none.
After the command is executed the job's end time, concurrency or pause time should be changed. If an already-succeeded job changes its end time, its status will become running.
Example:
$ oozie job -oozie http://localhost:8080/oozie -config job.properties -rerun 14-20090525161321-oozie-tucu
The rerun option reruns a completed ( SUCCCEDED , FAILED or KILLED ) job skipping the specified nodes.
The parameters for the job must be provided in a file, either a Java Properties file (.properties) or a Hadoop XML Configuration file (.xml). This file must be specified with the -config option.
The workflow application path must be specified in the file with the oozie.wf.application.path property. The specified path must be an HDFS path.
The list of nodes to skipped must be provided in the oozie.wf.rerun.skip.nodes property separated by commas.
After the command is executed the job will be in RUNNING status.
Refer to the Rerunning Workflow Jobs for details on rerun.
Example:
$oozie job -rerun <coord_Job_id> [-nocleanup] [-refresh] [-action 1, 3-4, 7-40] (-action or -date is required to rerun.) [-date 2009-01-01T01:00Z::2009-05-31T23:59Z, 2009-11-10T01:00Z, 2009-12-31T22:00Z] (if neither -action nor -date is given, the exception will be thrown.)
The rerun option reruns a terminated (=TIMEDOUT=, SUCCEEDED , KILLED , FAILED ) coordiantor action when coordiator job is not in FAILED or KILLED state.
After the command is executed the rerun coordiator action will be in WAITING status.
Refer to the Rerunning Coordinator Actions for details on rerun.

The info option can display information about a workflow job or coordinator job or coordinator action.
The offset and len option specified the offset and number of actions to display, if checking a workflow job or coordinator job.
The localtime option displays times in local time, if not specified times are displayed in GMT.
The verbose option gives more detailed information for all the actions, if checking for workflow job or coordinator job.
Example:
$ oozie job -oozie http://localhost:8080/oozie -definition 14-20090525161321-oozie-tucu<workflow-app xmlns="uri:oozie:workflow:0.2" name="sm3-segment-2413">

The dryrun option tests running a coordinator job with given job properties and does not create the job.
The parameters for the job must be provided in a file, either a Java Properties file (.properties) or a Hadoop XML Configuration file (.xml). This file must be specified with the -config option.
The coordinator application path must be specified in the file with the oozie.coord.application.path property. The specified path must be an HDFS path.
Example:
$ oozie jobs -oozie http://localhost:8080/oozie -localtime -len 2 -fliter status=RUNNING .

The jobs sub-command will display information about multiple jobs.
The offset and len option specified the offset and number of jobs to display, default values are 1 and 100 respectively.
The localtime option displays times in local time, if not specified times are displayed in GMT.
The verbose option gives more detailed information for each job.
A filter can be specified after all options.
The filter option syntax is: [NAME=VALUE][;NAME=VALUE]* .
Valid filter names are:
The query will do an AND among all the filter names. The query will do an OR among all the filter values for the same name. Multiple values must be specified as different name value pairs.
* This feature is only supported in Oozie 2.0 or later.

The jobtype option specified the job type to display, default value is 'wf'. To see the coordinator jobs, value is 'coordinator'.
Example:
$ oozie admin -oozie http://localhost:8080/oozie -status . Safemode: OFF
It returns the current status of the Oozie system.
* This feature is only supported in Oozie 2.0 or later.
Example:
$ oozie admin -oozie http://localhost:8080/oozie -systemmode [NORMAL|NOWEBSERVICE|SAFEMODE] . Safemode: ON
It returns the current status of the Oozie system.
Example:
$ oozie admin -oozie http://localhost:8080/oozie -version . Oozie server build version: 2.0.2.1-0.20.1.3092118008--
It returns the Oozie server build version.
* This feature is for administrator debugging purpose
Example:
$ oozie admin -oozie http://localhost:8080/oozie -queuedump[Server Queue Dump]: (coord_action_start,1),(coord_action_start,1),(coord_action_start,1) (coord_action_ready,1) (action.check,2)
It returns the Oozie server current queued commands.
Example:
$ oozie validate myApp/workflow.xml
.
Error: Invalid workflow-app, org.xml.sax.SAXParseException: cvc-complex-type.2.4.a:
Invalid content was found starting with element 'xend'. One of '{"uri:oozie:workflow:0.1":decision,

"uri:oozie:workflow:0.1":action, "uri:oozie:workflow:0.1":end}' is expected.
It performs an XML Schema validation on the specified workflow XML file.
* This feature is only supported in Oozie 2.0 or later.
Example:
$ oozie sla -oozie http://localhost:8080/oozie -len 1
.
<sla-message>
<event>
<sequence-id>1091</sequence-id>
<status>
<sla-id>0000004-100521225917912-oozie-wrkf-C@1</sla-id>

<job-status>STARTED</job-status>
<job-data />
</status>
</event>
<last-sequence-id>1091</last-sequence-id>
</sla-message>
The offset and len option specified the offset and number of sla events to display, default values are 1 and 100 respectively.
The return message is XML format that can be easily consumed by SLA users.
Example:
$ oozie pig -oozie http://localhost:8080/oozie -file pigScriptFile -config job.properties -X -param_file params . job: 14-20090525161321-oozie-tucu-W . $cat job.properties fs.default.name=hdfs://localhost:9000 mapreduce.jobtracker.kerberos.principal=ccc dfs.namenode.kerberos.principal=ddd oozie.libpath=hdfs://localhost:9000/user/oozie/pig/lib/
The parameters for the job must be provided in a Java Properties file (.properties). jobtracker, namenode, libpath must be specified in this file. pigScriptFile is a local file. All jar files (including pig jar file) and all other files needed by the pig job (e.g., parameter file in above example) need to be uploaded onto HDFS under libpath beforehand. The workflow.xml will be created in Oozie server internally. Users can get the workflow.xml from console or command line(-definition).
The job will be created and run right away.
