Event recovery failing - "Failed to load class com.snowplowanalytics.snowplow.event.recovery.Main."

Trying to run snowplow event recovery on Amazon EMR through the console. Below is screenshot of my setup. Jar being used is snowplow-event-recovery-spark-0.5.1.jar. When I try running it, get error Failed to load class com.snowplowanalytics.snowplow.event.recovery.Main (unfortunately EMR Studio doesn’t provide any other logging besides that message/no traceback). Has anyone run into this issue and found solution? Also, I tried w/ flink first and w/ that was getting error about being unable to find the main class
