Azure Data Lake Storage Gen1
This guide describes how to configure Alluxio with Azure Data Lake Storage Gen1 as the under storage system.
Azure Data Lake Storage is an enterprise-wide hyper-scale repository for big data analytic workloads. Azure Data Lake enables you to capture data of any size, type, and ingestion speed in one single place for operational and exploratory analytics. It is designed to store and analyze large amounts of structured, semi-structured, and unstructured data.
For more information about Azure Data Lake Storage Gen1, please read its documentation.
Note: Azure Data Lake Storage Gen1 will be retired on Feb 29, 2024. Be sure to migrate to Azure Data Lake Storage Gen2 prior to that date. See how here.
Prerequisites
If you haven’t already, please see Prerequisites before you get started.
In preparation for using Azure Data Lake Storage Gen1 with Alluxio, create a new Data Lake storage in your Azure account or use an existing Data Lake storage.
<AZURE_DIRECTORY> |
The directory you want to use, either by creating a new directory or using an existing one |
<AZURE_ACCOUNT> |
Your Azure storage account |
<CLIENT_ID> |
See Get application ID and authentication key for instructions on how to retrieve the application (client) ID and authentication key (also called the client secret) for your application |
<AUTHENTICATION_KEY> |
See Get application ID and authentication key for instructions on how to retrieve the application (client) ID and authentication key (also called the client secret) for your application |
<TENANT_ID> |
See Get tenant ID for instructions on how to retrieve the tenant ID |
You also need to set up Service-to-service authentication for your storage account.
Basic Setup
To use Azure Data Lake Storage Gen1 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.
$ cp conf/alluxio-site.properties.template conf/alluxio-site.properties
Specify the underfs address by modifying conf/alluxio-site.properties to include:
alluxio.dora.client.ufs.root=adl://<AZURE_ACCOUNT>.azuredatalakestore.net/<AZURE_DIRECTORY>/
Specify the application ID, authentication key and tenant ID for the Azure AD application used for the Azure account of the root mount point by adding the following
properties in conf/alluxio-site.properties:
fs.adl.account.<AZURE_ACCOUNT>.oauth2.client.id=<CLIENT_ID>
fs.adl.account.<AZURE_ACCOUNT>.oauth2.credential=<AUTHENTICATION_KEY>
fs.adl.account.<AZURE_ACCOUNT>.oauth2.refresh.url=https://login.microsoftonline.com/<TENANT_ID>/oauth2/token
After these changes, Alluxio should be configured to work with Azure Data Lake storage as its under storage system, and you can run Alluxio locally with it.
Running Alluxio Locally with Data Lake Storage
Once you have configured Alluxio to Azure Data Lake Storage Gen1, try running Alluxio locally to see that everything works.
