Nicholas Telford commented on HBASE-5208:
-----------------------------------------
Not entirely sure why there are (unrelated) tests failing. Looking at the
error, they all appear to be caused by the following. Can someone verify
whether or not this is caused by something in my patch?

As for the findbugs and JavaDoc issues: JavaDoc is reporting a negative number
of problems, so I'm disregarding it. Findbugs doesn't seem to be finding
anything in my new code, although it's difficult to be sure given the volume of
warnings.
> 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, HBASE-5208-002.txt,
> HBASE-5208-003.txt, HBASE-5208-004.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.
