Greetings, SPOT-286 points out that in scala-ml/src/main/scala/org/apache/spot/*/model/*.scala, there are calls to org.apache.spark.sql.functions.broadcast(), which is a performance optimization hint to the scala engine. The ticket identified at least one scenario where this hint causes a crash.
There is no harm to correctness from removing this optimization, and it fixes the crash. I recommend we remove this optimization until the matter is re-assessed later. Jeremy
