Nicholas Telford updated HBASE-5208:
------------------------------------
Release Note: Added "hbase.mapreduce.scan.row.start" and
"hbase.mapreduce.scan.row.stop" for defining start and stop rows for a
MapReduce job without having to serialize a Scan object.
Status: Patch Available (was: Open)
> 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
> Attachments: HBASE-5208-001.txt
>
>
> 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.
