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

             Summary: Stop-and-Start Upgrade: Fix for Oozie Express upgrade issues from HDP
2.1 to 2.3
                 Key: AMBARI-13824
                 URL: https://issues.apache.org/jira/browse/AMBARI-13824
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.0, 2.1.3
            Reporter: Swapan Shridhar
            Assignee: Swapan Shridhar
            Priority: Critical
             Fix For: 2.2.0, 2.1.3


Problem : Unable to start Ozzie server while on upgrade from HDP 2.1 -> 2.3.

Reason :  As 2.3 has symlinks instead of directory structure for "/etc/oozie/conf" and "usr/hdp/current/oozie-*/conf".


* -> "server" or "client"

The symlinks are not properly set for Ozzie Server and client after the upgrade. 

Resolution : Added a new class and comamnd "CONFIGURE_FUNCTION" to get the sym links working.

After the upgrade, the symlinks are :

================================================
/etc/oozie/conf -> /etc/oozie/2.3.4.0-3204/0
/usr/hdp/current/oozie-server/conf -> /etc/oozie/2.3.4.0-3204/0
================================================


P.S. The changes are generic in "conf_select" for setting the sym links. Thus, other services
also should be having their symlinks working in 2.1->2.3 upgrade path.
