HDFS HttpFS Authentication errors using current chart version

[loicdescotte]

When I install the current chart version like this :

helm install hdfs gradiant/hdfs, I am unable to use httpfs to create directories or files :

http://httpfs-host/webhdfs/v1/user/loic/test?op=MKDIRS&user.name=loic gives me a 500 Internal Server Error :

{
"RemoteException": {
"message": "User: hdfs is not allowed to impersonate loic",
"exception": "RemoteException",
"javaClassName": "org.apache.hadoop.ipc.RemoteException"
}
}

However, it is working when I'm using the 0.1.0 version like this :

helm install hdfs https://github.com/Gradiant/charts/releases/download/hdfs-0.1.0/hdfs-0.1.0.tgz

Hi loic,

There is a bug in the user impersonation configuration. We have changed the default admin user in hdfs image from rootto hdfs, but we have not updated the corresponding core-site.xml configuration to let hdfs user to impersonate other users.

With the latest release it should work.
