Allen Wittenauer commented on HADOOP-13123:
-------------------------------------------

That's a very good question.  I suspect the answer is yes, which definitely 
means HADOOP-12563 should get pulled back from branch-2.

> Permit the default hadoop delegation token file format to be configurable

> If one environment updates to using the new dtutil code and accompanying 
> Credentials code, there is a backward compatibility issue with the default 
> file format being JAVA.  Older clients need to be updated to ask for a file 
> in the legacy format (FORMAT_JAVA).  
> As an aid to users in this trap, we can add a configuration property to set 
> the default file format.  When set to FORMAT_JAVA, the new server code will 
> serve up legacy files without being asked.  The default value for this 
> property will remain FORMAT_PB.  But affected users can add this config 
> option to the services using the newer code.
