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.
