Carl updated HADOOP-18542:
--------------------------
    Description: 
The `AbfsConfiguration` class requires that we provide a tenant and client ID 
when using the `MsiTokenProvider` class to fetch an authentication token. The 
bug is that those fields are not required by the Azure API, which can infer 
those fields when the call is made from an Azure instance.

The fix is to make tenant and client ID optional when getting an Azure token 
from the Azure Metadata Service.

A fix has been submitted here: [https://github.com/apache/hadoop/pull/4262]

The bug was introduced with HADOOP-17725  
([https://github.com/apache/hadoop/pull/3041/files])
