https://issues.apache.org/jira/browse/AMBARI-13824
Repository: ambari
Description
-------
Stop-and-Start Upgrade: Fix for Oozie Express upgrade issues from HDP 2.1 to 2.3
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.
