> Currently, TableInputFormat initializes a serialized Scan from "hbase.mapreduce.scan".
Alternatively, it will instantiate a new Scan using properties defined in "hbase.mapreduce.scan.*".
However, of these properties the "start row" and "stop row" (arguably the most pertinent)
are missing.
> TableInputFormat should permit the specification of a start/stop row as with the other
fields using a new pair of properties: "hbase.mapreduce.scan.row.start" and "hbase.mapreduce.scan.row.end"
> The primary use-case for this is to permit Oozie and other job management tools that
can't call TableMapReduceUtil.initTableMapperJob() to operate on a contiguous subset of rows.
