Josh Elser resolved ACCUMULO-3556.
----------------------------------
    Resolution: Fixed

Improved message in Exception, in addition to creating a new, very detailed log message, to be clear in that the issue is in the client's code and not Accumulo's.

> Users complained that they started seeing "Scanner closed" messages after upgrading to 1.6. While, this was unexpected for them, it was indicative that they have bugs in their client code.
> We can make a better error message to inform the user that the problem is theirs' and not ours.
