-----------------------------------------------------------
Key: HDFS-2528
URL: https://issues.apache.org/jira/browse/HDFS-2528
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 0.20.205.0
Reporter: Arpit Gupta
Assignee: Tsz Wo (Nicholas), SZE
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 hrt12n23.cc1.ygridcore.net/98.137.234.231:8020 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.
