You could set "spark.jars.packages" in `conf` field of session post API (https://github.com/apache/incubator-livy/blob/master/docs/rest-api.md#post-sessions). This is equal to --package in spark-submit.

BTW you'd better ask livy question in user@livy.incubator.apache.org.

Hi

I have a python program which I invoke as 

 spark-submit --packages com.databricks:spark-avro_2.11:3.2.0 somefile.py  "2017-08-23 02:00:00"  and it works....

Now I want to submit this file using Livy. I could work out most of the stuff (like putting files to HDFS etc) but not able to understand how/where to configure the "packages" switch.......Any help?
