> the following exception is thrown by the datanode when the redirect happens.
> {"RemoteException":{"exception":"IOException","javaClassName":"java.io.IOException","message":"Call
to  failed on local exception: java.io.IOException: javax.security.sasl.SaslException: GSS
initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed

a file successfully.
