snvijaya opened a new pull request #1923: Hadoop 16857
URL: https://github.com/apache/hadoop/pull/1923
 
 
   AzureADAuthenticator includes retry logic for all oAuth token providers that are implemented
in ABFS Driver. Where as CustomTokenProvider failures end up in retry from the ABFS Driver
REST request invoking layer which is not expected. 
   
   Ideally custom token provider implementation should include retry logic too. Raising PR
to stop retries getting triggered from the REST op layer due to exceptions from custom token
provider.
   
   As custom token providers might have had benefited by the unintentional retry happening,
have retained a linear retry to trigger getAccessToken. The retry count is made configurable.
