> The sample JSON data snippet here (http://drill.apache.org/docs/kvgen/) needs to be corrected and additionally the SQL query to produce the output listed in that section, can be added to that section.
> Here is the correct representation of the data in the JSON data file. Currently the text on documentation page is missing the "rec1" identifier, and the opening and closing braces for "rec1" are also missing.
> {code}
> [root@centos-01 bin]# hadoop fs -cat /tmp/simplemaps.json
> {"rec1":{"a": "valA", "b": "valB"}}
> {"rec1":{"c": "valC", "d": "valD"}}
> {code}
> Query that produces the desired output, like the one mentioned in the documentation section for KVGEN function.
> {code}
> 0: jdbc:drill:> select kvgen(rec1) from `simplemaps.json`;
