Subject [jira] [Created] (HBASE-5208) Allow setting Scan start/stop row individually in TableInputFormat
Date Mon, 16 Jan 2012 13:10:40 GMT
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.
