Steve Loughran commented on HADOOP-14565:
-----------------------------------------
Based on the experience of WASB
# I'd like as realistic testing of this as possible, ideally even bringing up
some minimal REST endpoint to do it. Why? Ensures that the production codepath
gets tested before integration test time
# add lots of logging, diagnostics and timeouts here. See #1
> Azure: Add Authorization support to ADLS

> Key: HADOOP-14565
> URL: https://issues.apache.org/jira/browse/HADOOP-14565
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/adl
> Affects Versions: 2.8.0
> Reporter: Ryan Waters

> HADOOP_14565__Added_authorizer_functionality_to_ADL_driver.patch
>
>
> This task is meant to add an Authorizer interface to be used by the ADLS
> driver in a similar way to the one used by WASB. The primary difference in
> functionality being that the implementation of this Authorizer will be
> provided by an external jar. This class will be specified through
> configuration using "adl.external.authorization.class".
> If this configuration is provided, an instance of the provided class will be
> created and all file system calls will be passed through the authorizer,
> allowing implementations to determine if the file path and access type
> (create, open, delete, etc.) being requested is valid. If the requested
> implementation class is not found or it fails to initialize, it will fail
> initialization of the ADL driver. If no configuration is provided, calls to
> the authorizer will be skipped and the driver will behave as it did
> previously.
