Using Token-Based Authentication

To use token-based authentication:

Obtain a valid OAuth2 bearer token from the Azure Active Directory service for those valid users who have access to Azure Data Lake Storage account. The token must be obtained for a specific client ID in the application code. For more information, refer to Active Directory Library For Java.

Add the following properties to your core-site.xml:

<property>
  <name>fs.adl.oauth2.access.token.provider.type</name>
  <value>RefreshToken</value>
</property>

<property>
  <name>fs.adl.oauth2.client.id</name>
  <value>CLIENT-ID</value>
</property>

<property>
  <name>fs.adl.oauth2.refresh.token</name>
  <value>REFRESH-TOKEN</value>
</property>

Se the value of fs.adl.oauth2.access.token.provider.type to "RefreshToken" and set the other two parameters.

	Note
	Do not share the client ID or the refresh token. They must be kept secret.
