XXXXXXXXXX
Module 12 Quiz
Suppose we have a Z-Order Curve with interspersed latitudes and longitudes such that a point with latitude XXXXXXXXXXand longitude XXXXXXXXXXis represented by rowID XXXXXXXXXXLet us also say that latitude 90S (south pole) is represented by XXXXXXXXXXdegrees, the equator is represented by XXXXXXXXXXdegrees, and 90N (the north pole) is represented by XXXXXXXXXXdegrees. Let us say that longitude 180W is represented by XXXXXXXXXXdegrees, 90W is represented by XXXXXXXXXXdegrees, 0 is represented by XXXXXXXXXXdegrees, 90E is represented by XXXXXXXXXXdegrees, and 179.999E is represented by XXXXXXXXXXdegrees. Suppose further that the Accumulo table represents the name of the tourist site at that latitude and longitude. A sample schema for the Accumulo table that represents the Eiffel Tower in France XXXXXXXXXX, XXXXXXXXXXand the La Moneda Palace in Chile XXXXXXXXXX, XXXXXXXXXXis:
    rowID
    columnFamily
    columnQual
    time
    value
     XXXXXXXXXX
    site
    Eiffel Towe
    
    
     XXXXXXXXXX
    Site
    La Moneda Palace
    
    
Write the pseudocode for the Map and Reduce methods that find all points within a latitude-longitude bounding box. Remember that the bounds of the longitude may cross the 0 degree meridian. Part of the grade will be dependent on the efficiency of your MapReduce pseudocode. Remember that the rowID has an interleaved format for efficiency reasons.
1) Map pseudocode
Map (row[fromNode, family, toNode, time, weight]) {
2) Reduce pseudocode

Suppose we have a Z-Order Curve with interspersed latitudes and longitudes such that a point with latitude 33.333 and longitude 55.555 is represented by rowID 3535.353535. Let us also say that latitude 90S (south pole) is represented by 000.000 degrees, the equator is represented by 90.000 degrees, and 90N (the north pole) is represented by 180.000 degrees. Let us say that longitude 180W is represented by 000.000 degrees, 90W is represented by 90.000 degrees, 0 is represented by 180.000 degrees, 90E is represented by 270.000 degrees, and 179.999E is represented by 359.999 degrees. Suppose further that the Accumulo table represents the name of the tourist...
