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.
