Hi Jim, I have made those changes and I'm wondering if you can runs this be using the two .jar files that the "mvn package" places in the target directory?
I have tried to have Drill pick those up but the error now is: Error: SYSTEM ERROR: UnsupportedOperationException Fragment 0:0 [Error Id: da589dd4-4cfd-4659-8b93-219074ab8c72 on localhost:31010] (state=,code=0) It seems to indicate that it's picking up the functions but that they can not be run.
