Spark livy execution from nifi: livy-session are keep instantiating.

[#1]

Hi All,

I am running spark (livy) from nifi. Currently using HDP 3.0/HDF 3.1 the CDA version.

I was running spark livy through nifi. I could see that nifi flow was completed successfully. But there were several livy-session keep executing in Yarn. I've tried to kill some of them but they were re-appearing in Yarn. 

This is causing issue that these livy sessions are consuming CPUs even though I am not running any spark application through livy-nifi.

I am not sure how to resolve this issue. Needed your help here.

Hi @TimothySpann 

Could you please help here.

I don't recommend using the spark livy connector anymore.

Also by default it's not setup for use for anything other than zeppelin.

i would connect via kafka.

in nifi you can check the livy controller settings and make sure it's not respawning new ones.
