load Sharing across the regions

i have created the cluster with 3 region server and i used YCSB to test the
performance of the cluster.

https://github.com/brianfrankcooper/YCSB/tree/master/hbase098

Created the table as mentioned in the link with equal splits(pre split) in
the regions , But i noted that Load isn't equally shared among the regions.

Please guide me to achieve equal load across Regionserver.

Best,
Mahe

i have used workloada with 10000 record count, Initially i didn't split as
per  key "USER" i walkthrough the src ill resolved the load sharing .

But am getting only 7K request per sec is there any way to reach more
number of request . i need to check the threshold limit .

Thanks

Presplitting table allows load to spread across region servers.

Can you be more specific about what you observed ?

Which workload(s) did you run ?

Thanks
