>
> When AuthType and Auth token provider configs are set for both generic and 
> account specific config, as below:
> // account agnostic
> fs.azure.account.auth.type=CUSTOM
> fs.azure.account.oauth.provider.type=ClassExtendingCustomTokenProviderAdapter
> // account specific
> fs.azure.account.auth.type.account_name=OAuth
> fs.azure.account.oauth.provider.type.account_name=ClassExtendingAccessTokenProvider
>  For account_name, OAuth with provider as ClassExtendingAccessTokenProvider 
> is expected to be in effect.
> When the token provider class is being read from the config, account agnostic 
> config setting is read first in the assumption that it can serve as default 
> if account-specific config setting is absent. But this logic leads to failure 
> when AuthType set for account specific and otherwise are different as the 
> Interface implementing the token provider is different for various Auth 
> Types. This leads to a Runtime exception when trying to create the oAuth 
> access token provider.
> This Jira is to track the fix for it.
