Subject Kerberos impersonation of a Spark Context at runtime
Date Thu, 04 May 2017 09:13:54 GMT
Hi folks,

I have a Spark application executing various jobs for different users
simultaneously, via several Spark sessions on several threads.

My customer would like to kerberize his hadoop cluster. I wonder if there is
a way to configure impersonation such as each of these jobs would be ran
with the different proxy users. From what I see in spark conf and code, it's
not possible to do that at runtime for a specific context, but I'm not
familiar with Kerberos nor with this part of Spark.

Anyone can confirm/infirm this ?

Mathieu
