I'm a newbie and had a similar issue, in order to find out the right
principal for a service, I executed Wireshark on client or server node in a
test env... Wireshark kerberos dissector works quite well and tuo can see
details of requests, principals too. Perhaps this ke obvious but.. Not for
me :-
Hello, I am using Hadoop2.8 with Kerberos5 in the Docker, However I can
not access HDFS thought Kerberos ..The Docker image is
https://hub.docker.com/r/nlesc/xenon-hdfs-kerberos/
In the Docker container I have checked the `hdfs.keytab` by
> ```bash
> $ kinit -V -kt /opt/hadoop/hdfs.keytab hdfs/
Feng your best option is actually u...@hadoop.apache.org as the errors you
are seeing are over the hadoop classes within the JDK, which the team at
MIT does not produce. The openJDK as well as OracleJDK development teams
provide a kerberos implementation based on the standards established and
