I use hbase-0.98-5-hadoop2 and modify the default heap size of region
server in hbase-env.sh as below (keep all the other parameters in the file
default):
export HBASE_REGIONSERVER_OPTS=-Xmn200m
It works now by configuring the $JAVA_HOME explicitly.
The JAVA_HOME is configured as $JAVA_HOME by default. Now I configure it to
the complete path of my JDK explicitly.
A little strange here, the $JAVA_HOME is already set in the shell
environment, why do I still need to configure it again
Hi, Nick
Can your perf_blockcache performance testing script can be applied to hbase
cluster directly?
If not, what kind of things should I take care?

The scripts automate use of the tool PerformanceEvaluation that ships with
HBase, so in that way it runs against a cluster directly. It depends on
having independent configuration directories set up for each test
config. There's probably too much custom-to-my-environment stuff in there,
but I hope

Hi Zhaojie,
I'm responsible for this particular bit of work. One thing to note in these
experiments is that I did not control explicitly for OS caching. I ran
warmup workloads before collecting measurements, but because the amount
of RAM on the machine is fixed, it's impact of OS cache is

You can have a look if you are interested in.

In this result, the ratio of memory footprint to database size is held

I'm running random scan and put performance test at the same time, found that
put performance descend a lot. Don't know why.
Looking into the logs, found that Block cache LRU eviction occured almost
once per second. But it only last about 10 ms, so, will it bring so much
influence to put
