-----------------------------------------

             Summary: Oozie does not allow us to override hadoop credential provider factory at run time
                 Key: OOZIE-3180
                 URL: https://issues.apache.org/jira/browse/OOZIE-3180
             Project: Oozie
          Issue Type: Improvement
          Components: coordinator
    Affects Versions: 4.3.0, 4.2.0
            Reporter: Mahadevan Krishnan


It looks like we cannot override _hadoop_.security._credential_._provider_._path_ defined in oozie-site.xml at run time per application basis without making changes to oozie-site.xml and restarting oozie service?
 
 I am interested in defining my coordinator like this where I need to monitor for availability of file in the S3 bucket which is controlled by access key and secret access key. This access key and secret access key is maintained in application specific JCEK file and hence I cannot define _hadoop_.security._credential_._provider_._path_ in core-site.xml or oozie-site.xml and I will need to pass this property dynamically for each coordinator. I believe this flexibility is not there. Please help me understand if it is already available
