We are using MapR hadoop distribution with security enabled using maprticket. Do you have documents/steps to show how we can configure Dr. Elephant to work with secured MapR hadoop? 

 

I have installed it and the ui comes up but I am unable to see any spark jobs and the logs in logs/elephant/dr-elephant.log 

 

shows:

we are not using kerberos so I am unsure how to proceed from here
