Pramod Immaneni commented on APEXCORE-736:
------------------------------------------
The exception is thrown because yarn web services would expect the client to
authenticate with kerberos credentials and the client, in this case the
container, has none.

> Currently we are using a WebServicesClient in StreamingContainerManager to
> get container report from Yarn.
> Using the WebServicesClient will throw and exception if the webservices are
> kerberized.
> We should use a YARN client instead which can access kerberized YARN
> webservices as per its access levels.
