Hbase Read/Write poor performance. Please help!
Hello there, I'm running a read/write benchmark on a huge data (tweeter posts) for my school project.
The problem im dealing with is that the tests are going extreamly slow.
I dont know how to optimize the process. Hbase is using only about 10% of RAM memory, and 40% of CPU.
I've been experimenting with properties of hbase-site.xml file but I can't see any results. I think there is something I need to put in the API's code.
It's a single node, local operation. Virtual machine has 8GB RAM. Any help will be appreciated.
Best Regards - Kacper, student

Have you looked at the performance guidelines in our online book?

Can you post the client code you're using to read/write from HBase?
