    @cloud-fan Hi Wenchen, thanks for your comments. I went through the processing. I think its ok to just override equals and compare the udf class names here. The number of arguments, their semantic equality and deterministic property is handled in the semanticEquals method in expression.scala. Please let me know what you think.
