(Updated Oct. 15, 2014, 7:23 a.m.)
Review request for drill and Jason Altekruse.
Changes
-------
Updated patch so that function adds "key" field to the new map and doesn't add
"value" field in the case the value for the column is null in the original map
Repository: drill-git
Description
-------
Consider the following JSON:
{"x":{ "y": "kevin", "z": "paul" } }
Now this UDF would transform the map 'x' in the following manner
[ {"key":"y","value":"kevin"}, {"key":"z","value":"paul"}]
Currently this function only supports simple map as input and poses the
following two conditions on the values within the map
1. They should be of the same type
2. They can only be scalar types
