@skandtandon, can you share how you tested this patch?
If I understand correctly, with this patch, Livy will read some jars from user specific PVC. How do we add jars to the PVC in the first place? Are the jars replaced with new ones when we upgrade the app?

@sercanCyberVision the PVC is a place holder which is auto populated by the Livy server, so as far as my understanding goes, we won't be needing to place the jars in the PVC at all.
Sanity test was done on dev1 cluster by creating a similar PVC manually in Spark Namespace, and then running the livy session in spark namespace. The session ran successfully with older Spark image without the need to upload or maintain the jars

LGTM! Thank you @skandtandon
