> Currently, org.apache.hadoop.hbase.mapreduce.TableMapReduceUtil.initTableMapperJob()
forces any Hbase job to use the default TableInputFormat.class as the job's input format class.
> "job.setInputFormatClass(TableInputFormat.class);" ==> This line is included in initTableMapperJob().
> This restriction causes users to modify initTableMapperJob() in addition to implementing
their own TableInputFormat. 
> It would be nicer if users can use custom TableInputFormats without additionally tampering
with HBase source code.
