Hello there,
I am trying to write a UDF for Apache Drill which wraps a h2o MOJO but I'm running into a problem. When I copy h2o-genmodel.jar to the Drill path where you put jars, I get the following errors when I attempt to execute a query, regardless of whether the query has anything to do with h2o:

It seems that some library is conflicting with h2o-genmodel in Drill. Any suggestions?
