Zhihong Yu commented on HBASE-5208:
-----------------------------------

@Nicolas:
You should use --no-prefix to generate your patch so that Hadoop Qa can run it. 

This is a useful feature. Can you add a unit test for it ?

Thanks

> 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.
