We're using the normal command line:
---
bin/spark-submit --properties-file ./spark-submit.conf --class
com.rr.data.visits.VisitSequencerRunner
./mvt-master-SNAPSHOT-jar-with-dependencies.jar
---
Our jar contains both com.rr.data.visits.orc.OrcReadWrite (which you can
see in the stack trace) and the unfound com.rr.data.Visit.
I'll open a Jira ticket
