来源：互联网发布：js picker 编辑：程序博客网时间：2024/06/05 13:34

1. YCSB安装

wget https://github.com/downloads/brianfrankcooper/YCSB/ycsb-0.1.4.tar.gz
tar zxvf ycsb-0.1.4.tar.gz
cd ycsb-0.1.4
Or clone the git repository and build:
git clone git://github.com/brianfrankcooper/YCSB.git
cd YCSB
mvn clean package

2. 下载apache-cassandra-1.2.19-bin.tar.gz，根据README创建路径：

* tar -zxvf apache-cassandra-$VERSION.tar.gz
* cd apache-cassandra-$VERSION
* sudo mkdir -p /var/log/cassandra
* sudo chown -R `whoami` /var/log/cassandra
* sudo mkdir -p /var/lib/cassandra
* sudo chown -R `whoami` /var/lib/cassandra

3. 运行测试：

（1）进入cassandra源码目录bin，

执行：./cassandra -f

（2）另外开一个窗口执行./cassandra-cli，输入以下内容：

CREATE KEYSPACE usertable
with placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy'
and strategy_options = {replication_factor:2};
use usertable;
create column family data with comparator=UTF8Type and
default_validation_class=UTF8Type and key_validation_class=UTF8Type;

（3）进入ycsb/bin/执行

#./bin/ycsb load cassandra-10 -P workloads/workloadc -p threads=3 -p recordcount=100000 -p hosts=localhost -s >load.dat

#./bin/ycsb load cassandra-10 -P workloads/workloadc -p threads=3 -p recordcount=10000 -p hosts=127.0.0.1 -s >load.dat

bin/ycsb load cassandra-10 -P workloads/workloadc -p threads=<thread-numbers>
-p recordcount=<recorcount-value> -p hosts=<hostips> -s >load.dat
A few notes about this command:
 <thread-number> : the number of client threads, this is often done to increase the amount of
load offered against the database.
 <recorcount-value> : the total records for this benchmark. For example, when you want to
load 10GB data you shout set it to 10000000.
 <hostips> : the IP of cassandra’s nodes. If you have more than one node you should divide
with “,

ip地址写127.0.0.1

错误及解决办法：

SLF4J: Failed to load class “org.slf4j.impl.StaticLoggerBinder”

解决办法：下载slf4j-simple-1.6.2.jar放到ycsb-0.1.4/cassandra-binding/lib
