Description: 
Spark-Sql, {{CreateMap}} does not enforce unique keys, i.e. it's possible to 
create a map with two identical keys: 
{noformat}
CreateMap(Literal(1), Literal(11), Literal(1), Literal(12))
{noformat}

This does not behave like standard maps in common programming languages.
proper behavior should be chosen:
# first 'wins'
# last 'wins'
# runtime error.

{{GetMapValue}} currently implements option #1. Even if this is the desired 
behavior {{CreateMap}} should return a unique map.

  was:
Spark-Sql, CreateMap does not enforce unique keys, i.e. it's possible to create 
a map with two identical keys: 
CreateMap(Literal(1), Literal(11),
   Literal(1), Literal(12))

This does not behave like standard maps in common programming languages.
proper behavior should be chosen"
1. first 'wins'
2. last 'wins'
3. runtime error.

* currently GetMapValue implements option #1. even if this is the desired 
behavior CreateMap should return a unique map.
