Basic Setup
To use Aliyun OSS as the UFS of Alluxio root mount point, 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.
Specify an OSS bucket and directory as the underfs address by modifying conf/alluxio-site.properties
.
For example, the under storage address can be oss://alluxio-bucket/
if you want to mount the whole bucket to Alluxio, or oss://alluxio-bucket/alluxio/data
if only the directory /alluxio/data
inside the oss bucket alluxio-bucket
is mapped to Alluxio.
Specify credentials for Aliyun OSS access by adding the following properties in conf/alluxio-site.properties
:
