Builds on hdfs-client-onbuild.

This variant uses the same core-site.xml and krb5.conf files for ONBUILD COPY from the Onbuild Variant.

This variant contains the required client settings for xenon-hdfs-kerberos to work.

You will need to run nlesc/xenon-hdfs-kerberos with additional TCP + UDP port forwarding for port 88. So the docker run command should become:

docker run --detach --name=xenon-hdfs-kerberos --hostname xenon-hdfs-kerberos \
-p 88:88/tcp -p 88:88/udp -p 8020:8020 -p 50010:50010 -p 50470:50470 \
-p 50475:50475 nlesc/xenon-hdfs-kerberos

For this docker client, use kinit xenon instead of just kinit, and the password is javagat.

You are likely to require the use of docker run flag --net=host, since the ports to connect to are only exposed to the host.

For example:

docker run --net=host -it guangie88/hdfs-client-krb5-xenon:latest bash

Assuming that the image nlesc/xenon-hdfs-kerberos is running correctly, within the docker bash:

kinit xenon
hdfs dfs -df
hdfs dfs -ls /
