Configuring Alluxio with Minio
This guide describes how to configure Alluxio with Minio as the
under storage system. Alluxio natively provides the
s3a:// scheme (recommended for better performance). You can
use this scheme to connect Alluxio with Minio server.
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
$ cp conf/alluxio-site.properties.template conf/alluxio-site.properties
Minio is an object storage server built for cloud applications and DevOps. Minio provides an open source alternative to AWS S3.
Launch a Minio server instance using the steps mentioned here. Then create a bucket (or use an existing bucket). Once the server is launched, keep a note of Minio server endpoint, accessKey and secretKey.
You should also note the directory you want to use in that bucket, either by creating
a new directory in the bucket, or using an existing one. For the purposes of this guide, the Minio bucket name is called
MINIO_BUCKET, and the directory in that bucket is called
You need to configure Alluxio to use Minio as its under storage system by modifying
conf/alluxio-site.properties. The first modification is to specify an existing Minio
bucket and directory as the under storage system.
All the fields to be modified in
conf/alluxio-site.properties file are listed here:
alluxio.underfs.address=s3a://<MINIO_BUCKET>/<MINIO_DIRECTORY> alluxio.underfs.s3.endpoint=http://<MINIO_ENDPOINT>/ alluxio.underfs.s3.disable.dns.buckets=true alluxio.underfs.s3a.inherit_acl=false aws.accessKeyId=<MINIO_ACCESS_KEY_ID> aws.secretKey=<MINIO_SECRET_KEY_ID>
For these parameters, replace
<MINIO_ENDPOINT> with the hostname and port of your Minio service, e.g.,
http://localhost:9000. If the port value is left unset, it defaults to port 80 for
http and 443 for
