------------------------------------------------------------------
Posting from the user mailing list, one possible way to reproduce this issue:
# Define UDF in module, say in com.udf
# Create a topology using the above UDF in another module, say in org.test,
and start execution in org.test.
Only tested in locally, providing udfs as part of the jars on remote execution
could still work.
