Hi Everyone,

I am trying to develop a simple codebase on my machine to read data from secured Hadoop cluster. We have a development cluster which is secured through Kerberos and I want to run a Spark job from my IntelliJ to read some sample data from the cluster. Has anyone done this before ? Can you point me to some sample examples? 

I understand that, if we want to talk to secured cluster, we need to have keytab and principle. I tried using it through UserGroupInformation.loginUserFromKeytab and SparkHadoopUtil.get.loginUserFromKeytab but so far no luck. 

I have been trying to do this from quite a while ago. Please let me know if you need more info. Thanks

Regards,
Ajay
