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

             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
