> setConf() gets called in many places along the Map/Reduce chain.  HBase creates Tables
and etc in setConf in a few places.  There should be a better place to create the Table, often
while creating a TableRecordReader.
> This issue will tackle the following classes:
> - TableOutputFormatBase
> - TableInputFormatBase
> - TableInputFormat
> Other classes that could use a look over:
> - HRegionPartitioner
> - ReplicationLogCleaner
