Assuming you’re running on Ubuntu. We start with installing
Oracle Java 6
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install
oracle-java6-installer
Alternatively, install Java 1.6.0_23 (1.6.023 were tested by the CloudSuite authors):
http://diegobenna.blogspot.com/2011/01/install-jdk-6-update-21-in-ubuntu-1010.html
Note that although later Java
versions are also available, extra effort might be required to compile/run
Cassandra and YCSB if not using Java 6.
Make sure to set your $JAVA_HOME.
This can be done by
$ which java
In my case, the path is
/usr/bin/java, so I did
$ export JAVA_HOME=/usr
Next, install Apache Ant
$ sudo apt-get install ant
Ant (another neat tool), is a
tool for automating build, similar to Make (Ant:Java=Make:C/C++)
The next step is to download and
install YCSB. The package can be downloaded from here:
Although you can also clone
YCSB using git, the one on github doesn’t seem to have the appropriate
build.xml (build.xml is required for Ant). To make things easy, I use the
tarball.
Follow the steps from here to
build YCSB:
While building, keep in mind that
if you compile and run a program under different JDKs, an error will show up saying “Unsupported
major.minor version”. So just remember to use a Java version consistently.
You’ll also need to download and
install Cassandra. It can be found here:
Apache Cassandra is basically a
database management system. YCSB uses Cassandra to populate and operate on data
systems.
Similarly, although there are also later
versions of Cassandra, they are not always compatible with the Java/Ant/YCSB
version you’re using. For instance, there’ll be a stack size problem when
starting Cassandra if the Cassandra version and the Java version are not
compatible. So again, to make things easy, I use the tarball instead of installing it via Ubuntu deb.
To install and run Cassandra,
follow the steps in README inside the Cassandra directory. Alternatively, there
are some instructions here:
Now you should be ready to
generate a dataset. To do so
$ cd <path to cassandra>
$ ./bin/cassandra –f # this will
run Cassandra
Open another terminal
$ cd <path to cassandra>
$ ./bin/cassandra-cli -host localhost #
this will invoke the cli utility, which is connected your local-running
Cassandra
Upon entering the cassandra-cli prompt, use the commands provided in
Note that different versions of Cassandra use slightly different commands. In this example, we're using 0.73.
Note that different versions of Cassandra use slightly different commands. In this example, we're using 0.73.
Then, populate the database
$ cd <path to ycsb>
$ ./run_load.command # modify this shell script and
settings_load.dat accordingly
Finally, run the benchmark
$ ./run.command # modify this shell script and
settings.dat accordingly
