How to configure Kerberos authentication for HDFS type data source

Can someone help me with guidance how to connect to HDFS from Dremio using Kerberos?

thanks

@jaroslav_marko Have you look at this?

Yes we did, but it was not working with our setup. J

@jaroslav_marko

What is the error you are getting. Also Kerberos errors could be cryptic

To enable Kerberos debugging through dremio-env (not true on executors if Yarn deployment), restart coordinator

The DEBUG messages will go to server.out

DREMIO_JAVA_EXTRA_OPTS=-Dsun.security.krb5.debug=true 
 Dsun.security.spnego.debug=true -Djavax.net.debug=all

To enable Kerberos for executors if Yarn deployment

Open Dremio UI-Admin-Provisioning-Edit (use pencil icon)

Note: Provision only one container until problem is solved to reduce startup and shutdown time of containers

Under Additional properties, click add option and enter the 3 below,

Type: java
Name: sun.security.krb5.debug
value: true
Type: java
Name: sun.security.spnego.debug
value: true
Type: java
Name: javax.net.debug
value: all
