   I just reran the whole test suite on a fresh install, and this time 
everything passed, without changing the code 🤷 
   Note that I had switched to an HNS account last time already.
   The unit test you mention was failing on the implementation for the 
`ClientCredsTokenProvider`, which I hadn't changed (I only changed the logic 
for `MsiTokenProvider`), and was also failing when running from the upstream 
trunk branch.
   
   There might have been some build cache still using a broken version, it's 
kind of a mystery to me to be honest.
   
   Here is the output showing, feel free to run it yourself:

> 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])
