Subject Hbase random read performance
Date Mon, 08 Jul 2013 11:36:00 GMT
I'm trying to configure hbase for fully random read performance, my 
cluster parameters are:

9 servers as slaves, each has two 1TB HDD as hadoop volumes;
data:  800 millions 6-10 KB objects in hbase;

HBase Version - 0.90.6-cdh3u5
HBASE_HEAPSIZE=12288;
hfile.block.cache.size = 0.4
hfile.min.blocksize.size = 16384
hbase.regionserver.handler.count = 100

I used several recommended tuning solutions, such as
* tunrning on bloom filters;
* decreasing hbase block size to 16384.

However, read performance is still poor, about 800-1000rps.

What would you recommend to solve the problem?

Boris.
