      - Prerequisites for Using ADLS
        Setting up Azure Data Lake Store (ADLS) on the Azure portal enables you to access ADLS from any application.
      - Authenticating ADLS Account
        To access data stored in Azure Data Lake Store (ADLS), you must first authenticate your ADLS account using your ADLS credentials.
        Securely Providing ADLS Credentials
        You can provide your ADLS credentials securely by hiding the open, readable configuration on the command line using the Hadoop credential provider.
        Using ADLS for Data Input or Output
        You can use Azure Data Lake Store (ADLS) as a source or destination for your application data.

Securely Providing ADLS Credentials

You can provide your ADLS credentials securely by hiding the open, readable configuration on the command line using the Hadoop credential provider.

Procedure

Generate a jceks file for ADLS authorization:

hadoop credential create dfs.adls.oauth2.client.id -provider jceks://hdfs/user/USER_NAME/adlskeyfile.jceks -value client ID
hadoop credential create dfs.adls.oauth2.credential -provider jceks://hdfs/user/USER_NAME/adlskeyfile.jceks -value client secret
hadoop credential create dfs.adls.oauth2.refresh.url -provider jceks://hdfs/user/USER_NAME/adlskeyfile.jceks -value refresh URL

Run the DistCp example using the jceks file:

hadoop distcp
[-D hadoop.security.credential.provider.path=localjceks://hdfs/user/USER_NAME/adlskeyfile.jceks]
hdfs://<NameNode Hostname>:9001/user/foo/007020615
adl://<Account Name>.azuredatalakestore.net/testDir/

Configure the core-site.xml file to use the jceks file:

<property>
  <name>hadoop.security.credential.provider.path</name>
  <value>localjceks://hdfs/user/USER_NAME/adlskeyfile.jceks</value>
  <description>Path to interrogate for protected credentials.</description>
</property>
