Hi, We wanted to extend the existing '===' on Column to support deep equals on Maps.
Currently it checks for == which does referential checks for maps. https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/predicates.scala#L420 Is there any possible work around for this? I have a patch in my mind to fix Equals for MapType also. Any thoughts? Thanks, Lakshmi Rajagopalan
