To check the status of the job, following commands can be used.


-auth <arg> select authentication type [SIMPLE|KERBEROS]
-doas <arg> doAs user, impersonates as the specified user.
-filter <arg> user = <U>; name = <N>; group = <G>; status = <S>; ...
-jobtype <arg> job type ('Supported in Oozie-2.0 or later versions ONLY -
coordinator' or 'wf' (default>
>
-len <arg> number of jobs (default '100'>
-localtime use local time (default GMT>
-offset <arg> jobs offset (default '1'>
-oozie <arg> Oozie URL -verbose verbose mode


For example − To check the status of the Oozie system you can run the following command −

oozie admin -oozie http://localhost:8080/oozie -status

Validating a Workflow XML −
oozie validate myApp/workflow.xml

It performs an XML Schema validation on the specified workflow XML file.
