Running Alluxio on a Cluster
Download Alluxio
First download the Alluxio tar file, and extract it.
wget http://alluxio.org/downloads/files/1.5.0/alluxio-1.5.0-bin.tar.gz
tar xvfz alluxio-1.5.0-bin.tar.gz
Configure Alluxio
In the ${ALLUXIO_HOME}/conf directory, create the conf/alluxio-site.properties configuration
file from the template.
cp conf/alluxio-site.properties.template conf/alluxio-site.properties
Update alluxio.master.hostname in conf/alluxio-site.properties to the hostname of the machine
you plan to run Alluxio Master on. Add the IP addresses of all the worker nodes to the
conf/workers file. Finally, sync all the information to worker nodes. You can use
./bin/alluxio copyDir <dirname>
to sync files and folders to all hosts specified in the alluxio/conf/workers file.
Start Alluxio
Now, you can start Alluxio:
cd alluxio
./bin/alluxio format
./bin/alluxio-start.sh # use the right parameters here. e.g. all Mount
# Notice: the Mount and SudoMount parameters will format the existing RamFS.
To verify that Alluxio is running, you can visit http://<alluxio_master_hostname>:19999, check the
log in the directory alluxio/logs, or run a sample program:
./bin/alluxio runTests
Note: If you are using EC2, make sure the security group settings on the master node allows incoming connections on the alluxio web UI port.
