Subject [jira] [Commented] (AMBARI-14122) "Falcon - Oozie Integration" property are not populated and marked Mandatory After Upgrade
Date Tue, 01 Dec 2015 06:43:10 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-14122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15033191#comment-15033191
] 

Swapan Shridhar commented on AMBARI-14122:
------------------------------------------

Reason for this behavior :
--------------------------------

* In DELETE operation of 'upgrade-<version>.xml', we specifically direct to retain certain
properties for Oozie-falcon integration using 'keep-key' directive. 
* That's the place we ask it to retain the following 7 properties which become the source
of problem, as they don't exist and 'keep-key' was actually creating them, and finally they
were there without any value associated with them.

    oozie.service.ELService.ext.functions.coord-job-submit-instances, oozie.service.ELService.ext.functions.coord-action-create-inst,

    oozie.service.ELService.ext.functions.coord-action-create, oozie.service.ELService.ext.functions.coord-job-submit-data,
    oozie.service.ELService.ext.functions.coord-action-start, oozie.service.ELService.ext.functions.coord-sla-submit,
 
    oozie.service.ELService.ext.functions.coord-sla-create

* The properties are part of the 'falcon-oozie integration', and this problem surfaces only
when we are upgrading and "Falcon" service is not present. We were adding them, without checking
whether these properties themselves exist at the first place.

Fix : 
----

Fixed the code in ConfigureAction.java where in case of DELETE, it checks for 'key' existence
before adding/retaining it as part of 'keep-key' in Upgrade.

> * While doing Express/Rolling upgrade, with Oozie as one of the service and specifically
excluding FALCON as one of the service, a new set of 7 properties under "Falcon - Oozie Integration"
are introduced. 
> * They are marked 'mandatory' but don't have a value associated. Therefore, these properties
get shown as RED on UI (as they are mandatory.)
