> HIVE-6707 fixed an issue with lazy maps. Lazy maps scans for keys using key separators
and maintains a counter for the number of keys i.e; map size. However keys may include duplicates
in which returning the number of keys for map size will be wrong as after deserialization
the actual map will not have duplicate keys.
> This is a subtask of HIVE-6707 to fix the getMapSize() api.
