I hope this is the right list; I wasn't sure whether to post here or to the HDFS list.
I am using hadoop-azure version 3.3.1. I have a service deployed to Azure on an App Service Plan. When using MsiTokenProvider as the authentication mechanism, I am not able to authenticate. The root of this issue is that the way one gets a token in an App Service Plan is different from a regular Azure VM (see here: https://dev.to/stratiteq/managed-identity-how-it-works-behind-the-scenes-co4 ). Currently MsiTokenProvider requests a token using IMDS, but this will not work if it is doing so from an App Service Plan because the endpoint, and the expected headers and query-parameter values are entirely different. A workaround I am investigating is using a custom access token provider, but it would be nice if this came out of the box with hadoop-azure (or at least a way to tell hadoop-azure to use the token endpoint instead of IMDS when in an App Service Plan).
