------------------------------
Description:
curl -L -u : --negotiate -i "http://NN:50070/webhdfs/v1/tmp/webhdfs_data/file_small_data.txt?op=OPEN"
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 to find any Kerberos tgt)]"}}
Interestingly when using ./bin/hadoop with a webhdfs path we are able to cat or tail a file successfully.
