Configuring Alluxio with NFS
This guide describes the instructions to configure NFS as Alluxio’s under storage system.
Initial Setup
First, the Alluxio binaries must be on your machine. You can either compile Alluxio, or download the binaries locally.
Configuring Alluxio
You need to configure Alluxio to use under storage systems by modifying
conf/alluxio-site.properties. If it does not exist, create the configuration file from the
template.
cp conf/alluxio-site.properties.template conf/alluxio-site.properties
Assuming the NFS clients are co-located with Alluxio nodes, all the NFS shares are mounted at
directory /mnt/nfs, the following environment variable assignment needs to be added to
conf/alluxio-site.properties:
alluxio.underfs.address=/mnt/nfs
Running Alluxio with NFS
After everything is configured, you can start up Alluxio locally to see that everything works.
./bin/alluxio format
./bin/alluxio-start.sh local
This should start an Alluxio master and an Alluxio worker. You can see the master UI at http://localhost:19999.
Next, you can run a simple example program:
./bin/alluxio runTests
After this succeeds, you can visit your NFS volume to verify the files and directories created by Alluxio exist. For this test, you should see files named like:
/mnt/nfs/default_tests_files/Basic_CACHE_THROUGH
To stop Alluxio, you can run:
./bin/alluxio-stop.sh local
