Hi,
I'd like to do some benchmarks fo HBase but I don't know what tool
could use. I started to make some code but I guess that there're some
easier.
I've taken a look to JMeter, but I guess that I'd attack directly from
Java, JMeter looks great but I don't know if it fits well in this
scenario. W
You can use ycsb for this purpose.See here

Guillermo:
If you use hbase 0.98.x, please consider Andrew's ycsb repo:

I was checking that web, do you know if there's another possibility
since last updated for Cassandra was two years ago and I'd like to
compare bothof them with kind of same tool/code.

Maybe ask on Cassandra mailing list for the benchmark tool they use ?

Is there any result with that benchmark to compare??
I'm executing the different workloads and for example for 100% Reads
in a table with 10Millions of records I only get an performance of
2000operations/sec. I hoped much better performance but I could be
wrong. I'd like to know if it's a normal pe
What's the value for hfile.block.cache.size ?
By default it is 40%. You may want to increase its value if you're using
default.
Andrew published some ycsb results :
http://people.apache.org/~apurtell/results-ycsb-0.98.8/ycsb
-0.98.0-vs-0.98.8.pdf
However, I couldn't access the above now.

Yes, I'm using 40%. i can't access to those data either.
I don't know how YSCB executes the reads and if they are random and
could take advange of the cache.
Do you think that it's an acceptable performance?

How many instances of ycsb do you run and how many threads do you use per
instance.I guess these ops are per instance and you should get similar
numbers if you run more instances.In short try running more workload
instances...

You are hitting hbase harder now which is important for benchmarking.If
there is no data loss it means your hbase cluster is good enough to handle
the load.You are simply making more use of the cores from where you launch
ycsb process.Write your own workload depending on the record sizes,format
