    ACCUMULO-1732 Using table id in RangeInputSplit so that it can be resolved back to "working"
table name in mappers. Scanner uses the "working" table name while everything else can still
safely use the original configured table name.

    Removing deprecation for now until we have some discussions. Updating/adding comments.

    The legacy mapred InputFormatBase now verifies (and fixes the scanner for) a possible
change in table name that could happen between the configuration of the map/reduce job and
the actual processing of the scanner for a specific split. In that case, the most recent table
name associated with the id is always used for the scanner (though the table name that was
expected during job setup is still used in the RangeInputSplit). ACCUMULO-391

    The original single-table setters/getters now populate a "default" TableQueryConfig object
under the hood. This should make the switch over much easier. Deprecated single table methods
in light of the API changes for the new configuration object. ACCUMULO-391

    Adding new TableQueryConfig object for setting multiple table info in the InputFormatBase

I would see it making the table the mapper's key and making the Key/Value a tuple, or alternatively
have the Table/Key be the key tuple and stick with Values being the value.
