   For MSITokenProvider, there are 4 mandatory fields that need to be provided 
- The clientid,  authEndPoint, tenantGuid and authority, The authEndPoint and 
authority configs are missing here. Can you please try once by adding these 
config values as well ?

> It would be good to improve error messages for token providers in ABFS. 
> Currently, when a configuration key is not found or mistyped, the error is 
> not very clear on what went wrong. It would be good to indicate that the key 
> was required but not found in Hadoop configuration when creating a token 
> provider.
> For example, when running the following code:
> {code:java}
> import org.apache.hadoop.conf._
> import org.apache.hadoop.fs._
> val conf = new Configuration()
> conf.set("fs.azure.account.auth.type", "OAuth")
> conf.set("fs.azure.account.oauth.provider.type", 
> "org.apache.hadoop.fs.azurebfs.oauth2.ClientCredsTokenProvider")
> conf.set("fs.azure.account.oauth2.client.id", "my-client-id")
> // 
> conf.set("fs.azure.account.oauth2.client.secret.my-account.dfs.core.windows.net",
>  "my-secret")
> conf.set("fs.azure.account.oauth2.client.endpoint", "my-endpoint")
> val path = new Path("abfss://[email protected]/")
> val fs = path.getFileSystem(conf)
> fs.getFileStatus(path){code}
> The following exception is thrown:
> {code:java}
> TokenAccessProviderException: Unable to load OAuth token provider class.
> ...
> Caused by: UncheckedExecutionException: java.lang.NullPointerException: 
> clientSecret
> ...
> Caused by: NullPointerException: clientSecret {code}
> which does not tell what configuration key was not loaded.
>  
> IMHO, it would be good if the exception was something like this:
> {code:java}
> TokenAccessProviderException: Unable to load OAuth token provider class.
> ...
> Caused by: ConfigurationPropertyNotFoundException: Configuration property 
> fs.azure.account.oauth2.client.secret not found. {code}
