Review request for Ambari, Nate Cole and Tom Beerbower.
Bugs: AMBARI-9339
https://issues.apache.org/jira/browse/AMBARI-9339
Repository: ambari
Description
-------
During a downgrade, the Oozie scripts need to understand that a downgrade is
occurring. This is because there is a step that happens before {{prepare-war}}
where {{hadoop-lzo*.jar}} is copied to a location so that {{prepare-war}} can
use it.
However, hadoop-lzo*.jar does not exist in HDP 2.2.0.0 and does exist in
2.2.1.0.
The oozie scripts should produce an error if this file is not found and that is
correct - but only for upgrade.
This is part of a larger issue where the upgrade/downgrade status needs to be
available for the scripts. It currently is not.
