----------------------------------------------------------------
Tom, SQOOP-384 lists four mapreduce APIs needed by sqoop, and you've included
all four of them in this patch. However, they also need a different signature
of org.apache.hadoop.conf.Configuration.getInstances, as discussed in

and shown in the patch attached to that jira.
Can you add that API to this patch, please?

> Port missing new API mapreduce lib classes to 1.x

> Key: MAPREDUCE-3607
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3607
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: client
> Affects Versions: 1.0.0
> Reporter: Tom White
> Assignee: Tom White
> Attachments: MAPREDUCE-3607.patch, MAPREDUCE-3607.patch

> There are a number of classes under mapreduce.lib that are not present in the
> 1.x series. Including these would help users and downstream projects using
> the new MapReduce API migrate to later versions of Hadoop in the future.
> A few examples of where this would help:
> * Sqoop uses mapreduce.lib.db.DBWritable and
> mapreduce.lib.input.CombineFileInputFormat (SQOOP-384).
> * Mahout uses mapreduce.lib.output.MultipleOutputs (MAHOUT-822).
> * HBase has a backport of mapreduce.lib.partition.InputSampler and
> TotalOrderPartitioner (in org.apache.hadoop.hbase.mapreduce.hadoopbackport) -
> it would be better if it used the ones in Hadoop.
