find_model_collaborative.py job failed

[joshuarcher]

Initially the job ran on dataproc failed on line 60 of find_model_collaborative.py because the 'load' call was deprecated. Instead I changed that line to:
dfRates = sqlContext.read.load(source='jdbc', driver=jdbcDriver, url=jdbcUrl, dbtable='Rating')

ran the job again, came back with another error "java.util.NoSuchElementException: key not found: path" in callstack:
