>    Affects Versions: 2.8.0

> The default is 0, so any communication failure results in a client failure.  
> Oozie doesn't like that.  If the RM is failing over and Oozie gets a 
> communication failure, it assumes the target job has failed.  I propose 
> raising the default to something modest like 3 or 5.  The default retry 
> interval is 2s.
