The difference between the MAP and STRUCT data type in Hive is
A - MAP is Key-value pair but STRUCT is series of values
B - There can not be more than one MAP dat type column in a table but more than one STRUCT
data type in a table is allowed.
C - The Keys in MAP can not be integers but in STRUCT they can be.
D - Only one pair of data types is allowed in the key-value pair of MAP while mixed types are
allowed in STRUCT.
