Major Description
I have setup livy in a kerberized environment and have impersonation disabled (livy.impersonation.enabled = false). I can't use impersonation due to access issue with the proxy user.
Hence, jobs have to send their principal and keytab using the spark configs "spark.yarn.principal" and "spark.yarn.keytab". In my testing, I found that spark.yarn.keytab only accepts local file and the keytab file would need to reside on the same server as the livy service. However, I would like to allow remote access to the livy endpoint, which the keytab would then be on a remote machine.
Hence, I would like to check how to submit the keytab remotely. I have tried using the files parameter but could not get it to work.
