> Implement a Cassandra aware Hadoop mapreduce.Partitioner

>                 Key: CASSANDRA-1473
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1473
>             Project: Cassandra
>          Issue Type: Improvement
>          Components: Hadoop
>            Reporter: Stu Hood
>
> When using a IPartitioner that does not sort data in byte order 
> (RandomPartitioner for example) with Cassandra's Hadoop integration, Hadoop 
> is unaware of the output order of the data.
> We can make Hadoop aware of the proper order of the output data by 
> implementing Hadoop's mapreduce.Partitioner interface: then Hadoop will 
> handle sorting all of the data according to Cassandra's IPartitioner, and the 
> writing clients will be able to connect to smaller numbers of Cassandra nodes.
