Allow setting Scan start/stop row individually in TableInputFormat
------------------------------------------------------------------
Key: HBASE-5208
URL: https://issues.apache.org/jira/browse/HBASE-5208
Project: HBase
Issue Type: Improvement
Components: mapreduce
Reporter: Nicholas Telford
Priority: Minor
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.
