To run the Jenkins faster, I create a standalone PR instead of making a PR to #22821 . |

What changes were proposed in this pull request?
This PR aims to supercede #22821 . The main author is @cloud-fan .
According to the discussion in RC4 voting thread and SPARK-25829, Spark current has a very weird behavior when we have duplicated keys in map. The newly added map-related functions in Apache Spark 2.4.0 make it worse. For instance,
map_filtermay return incorrect result like SPARK-25823Before we entire fix the map behavior, we should not expose these functions to users.
How was this patch tested?
Pass the Jenkins.
