   > It's just that the relatively casual approach to hanging onto credentials 
here for performance seems to contrast with the aggressive approach to clearing 
security-related fields that you proposed in 
https://github.com/apache/accumulo/pull/2616, and I'm not sure how to reconcile 
the two approaches with a single coherent "security" principle.
   
   #2616 is about the encryption keys, but your point is fair. If 
@keith-turner's solution to the locking problem in #2700 is enough to solve the 
problem in the ScanServer and this is not needed, then I think we should not 
merge it. If this does help, I don't see it as any worse than storing the 
credentials in the likely longer-lived Session objects.
