Subject Size of a Hive Map column in characters!
Date Fri, 06 Dec 2013 13:42:11 GMT
The size(map) function is defined as follows: size(Map<K.V>) 	Returns the number of elements
in the map type

What if I want the total size of the map for that row?  This doesn't work: select length(MAP);

How can I get the total size of a map column in either bytes or characters?
