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

Found the proper link 
(http://hudson.zones.apache.org/hudson/job/Mapreduce-Patch-vesta.apache.org/383/artifact/trunk/patchprocess/releaseAuditDiffWarnings.txt).
 The audit warning is in mapred-default.xml which I changed to add 
{{sqoop.conn.factories}}. If this file hasn't already had a license stamp, then 
this is not the time to add it...

> Sqoop uses the ConnFactory class to instantiate a ConnManager implementation 
> based on the connect string and other arguments supplied by the user. This 
> allows per-database logic to be encapsulated in different ConnManager 
> instances, and dynamically chosen based on which database the user is 
> actually importing from. But adding new ConnManager implementations requires 
> modifying the source of a common ConnFactory class. An indirection layer 
> should be used to delegate instantiation to a number of factory 
> implementations which can be specified in the static configuration or at 
> runtime.
