I just added a patch to HBASE-987
https://issues.apache.org/jira/browse/HBASE-987
it has a Partitioner in to to group the records in to a reducer per region
you can set it as the partitioner in the job I am not sure if it will work
for 0.17
But you can give it a try the file in the patch you are looking for is
HRegionPartitioner.java

Hi ,
I'm using hbase0.2.1 + hadoop 0.17 with 11 client & 1master servers
I crawl some data and save them to hbase with map & reduce.
after that , I try to count the total number of some data.
it too slow , you can see the monitor , 1 of clients have a high request ,
but others is 0.
