Andras Piros commented on OOZIE-3385:
-------------------------------------
[~luguangming] the submitting user [is defined by the {{user.name}}
property|https://oozie.apache.org/docs/5.0.0/WorkflowFunctionalSpec.html#a6_User_Propagation]
of the submitted {{workflow.xml}} / {{job.properties}}. While submitting a
workflow / coordinator / bundle job, setting the HTTP parameter
{{oozie.user.name}} would override the one given in the workflow configuration.
There are other possibilities of [user
authentication|https://oozie.apache.org/docs/5.0.0/AG_Install.html#Oozie_User_Authentication_Configuration],
though. I'd recommend to do {{klist}} just before job submission - you might
have been authenticated as another user. Checking the exact CLI command might
also be helpful.
